[0009] First, embodiments of the present disclosure will be listed and described. The cooling garment of the present disclosure comprises: [1] A cooling suit to be worn by a user, comprising a clothing body, a cooling material storage section capable of storing a cooling material and attached to the clothing body, and an insulating section attached to the clothing body, wherein the insulating section is interposed between the clothing body and the cooling material storage section, and when the cooling suit is worn by the user, the cooling material storage section is positioned closer to the user than the insulating section.

[0010] According to this configuration, when the cooling suit is worn by a user, the cooling material storage compartment is located closer to the user than the insulating material. Therefore, the cooling material stored in the cooling material storage compartment can cool the user's body. Furthermore, the insulating portion is interposed between the clothing body and the cooling material storage compartment. This reduces heat conduction from the clothing body to the cooling material, and reduces the impact of heat from the clothing body on the cooling material. This improves the cooling duration of the cooling suit.

[0011] [2] When the cooling suit is worn by the user, the cooling material storage section has a surface layer that faces the user, and the surface layer is preferably mesh-like.

[0012] According to this configuration, the surface layer of the coolant storage unit is mesh-like, which allows air cooled by the coolant inside the coolant storage unit to easily pass through the surface layer of the coolant storage unit, thereby improving the cooling performance of the cooling suit.

[0013] [3] It is preferable that the coolant storage section has an opening through which the coolant can be put in and taken out, and an opening / closing structure configured to be able to open and close at least a part of the opening.

[0014] According to this configuration, the coolant storage unit has an opening that allows the coolant to be put in and taken out, and an opening / closing structure that allows at least a portion of the opening to be opened and closed. Therefore, when storing the coolant in the coolant storage unit, the opening can be opened using the opening / closing structure, allowing the coolant to be stored in the coolant storage unit. Furthermore, after the coolant has been stored in the coolant storage unit, the opening can be closed using the opening / closing structure, preventing the coolant from falling out of the opening. This improves the convenience of the cooling suit.

[0015] [4] The opening and closing structure is preferably a linear fastener.

[0016] According to this configuration, the opening and closing structure is a linear fastener. When the opening and closing structure is a linear fastener, it is possible to prevent the user from touching the opening and closing structure and unintentionally opening the opening when putting on the cooling suit, compared to when the opening and closing structure is a hook-and-loop fastener or a button. Therefore, it is possible to prevent the cooling material from falling out of the cooling suit.

[0017] [5] It is preferable that the garment body has a back body, and the cooling material storage section has a back body cooling material storage section provided in the back body.

[0018] According to this configuration, the cooling material storage section includes a rear cooling material storage section provided in the rear body. This allows the user's body to be cooled from the rear side, without restricting the range of motion of the user's arms. This prevents a decrease in the user's workability while wearing the cooling suit.

[0019] [6] The rear body cooling material storage section preferably has a first rear body cooling material storage section and a second rear body cooling material storage section.

[0020] According to this configuration, the rear body cooling material storage section has a first rear body cooling material storage section and a second rear body cooling material storage section. This allows the user to selectively store cooling material in the rear body cooling material storage section that corresponds to the part of their body they wish to cool. This allows the user to more flexibly adjust the cooling performance of the cooling suit, improving the convenience of the cooling suit.

[0021] [7] It is preferable that each of the first rear body cooling material storage section and the second rear body cooling material storage section has a rear body opening through which the cooling material can be put in and taken out, and that the rear body opening of the first rear body cooling material storage section faces the opposite side to the second rear body cooling material storage section, and that the rear body opening of the second rear body cooling material storage section faces the opposite side to the first rear body cooling material storage section.

[0022] According to this configuration, the rear opening of the first back body cooling material storage section faces away from the second back body cooling material storage section, and the rear opening of the second back body cooling material storage section faces away from the first back body cooling material storage section. When a user stores a cooling material in the first back body cooling material storage section, the first back body cooling material storage section expands by the amount of cooling material. Because the rear opening of the second back body cooling material storage section faces away from the first back body cooling material storage section, the user can store the cooling material in the second back body cooling material storage section more easily than if it were facing the first back body cooling material storage section. This improves the convenience of the cooling suit.

[0023] [8] It is preferable that the insulating portion has a first region and a second region spaced apart from the first region, and that the garment body has greater elasticity than the first region of the insulating portion and greater elasticity than the second region of the insulating portion.

[0024] According to this configuration, the garment body has greater stretchability than the first region of the thermal insulation section and greater stretchability than the second region of the thermal insulation section. Therefore, in the region where there is no thermal insulation section, the garment body stretches, which prevents a decrease in stretchability of the cooling garment. Therefore, a decrease in comfort for the user wearing the cooling garment can be prevented.

[0025] [9] The insulation section has a first separate insulation section and a second separate insulation section separated from the first separate insulation section, the first separate insulation section being interposed between the first rear body cooling material storage section and the rear body, and the second separate insulation section being interposed between the second rear body cooling material storage section and the rear body, and it is preferable that the rear body has greater elasticity than the first separate insulation section and greater elasticity than the second separate insulation section.

[0026] With this configuration, the back body has greater stretchability than both the first and second separate insulation sections. Therefore, in areas where the first and second separate insulation sections are not present, the back body stretches, preventing a decrease in stretchability of the cooling suit. This prevents a decrease in comfort for the user wearing the cooling suit.

[0027]

[10] The clothing body has sleeve openings, which have a first sleeve opening through which one arm of the user passes when the cooling suit is worn by the user, and a second sleeve opening located on the opposite side of the first sleeve opening through which the other arm of the user passes, and it is preferable that the first and second separate insulation sections are aligned in the same direction as the first and second sleeve openings when viewed from the front.

[0028] According to this configuration, the first and second separate insulation sections are aligned in the same direction as the first and second armholes when viewed from the front. Therefore, in the back body, the first and second separate insulation sections are spaced apart from the second separate insulation section in the same direction as the first and second armholes. That is, when a user wearing the cooling suit stretches their arms forward, the first and second separate insulation sections are spaced apart from the second separate insulation section in the same direction as the back body stretches. This prevents restrictions on the range of motion of the user's arms and reduces the user's workability while wearing the cooling suit.

[0029]

[11] It is preferable that the garment body has a front body, and the cooling material storage section has a front body cooling material storage section provided in the front body.

[0030] According to this configuration, the cooling material storage section includes a front body cooling material storage section provided in the front body, which allows the user's body to be cooled from sides other than the back, thereby improving the cooling performance of the cooling suit.

[0031]

[12] When the cooling suit is worn by the user, it is preferable that the cooling material storage section contacts the user's sides and the rear cooling material storage section contacts the user's back, and that the surface layer of the front cooling material storage section is thicker than the surface layer of the rear cooling material storage section.

[0032] According to this configuration, the surface layer of the front body cooling material storage section is thicker than the surface layer of the back body cooling material storage section. Because the armpits have a higher blood flow rate than the back, the cooling efficiency of the body is superior. However, if the armpits and back are cooled with the same cooling material, some users of the cooling suit may feel that the armpits are overcooled. However, changing the type of cooling material for each cooling target is undesirable from the perspective of user convenience. By making the surface layer of the front body cooling material storage section thicker than the surface layer of the back body cooling material storage section, the user does not need to select the type of cooling material depending on the degree of cooling of their body. Therefore, the convenience of the cooling suit can be improved.

[0033]

[13] When the cooling suit is worn by the user, the user can select between a first wearing state and a second wearing state of the cooling suit, and in the first wearing state, the cooling material storage unit preferably contacts at least one of the user's back and waist, and in the second wearing state, the cooling material storage unit preferably contacts the user's neck.

[0034] According to this configuration, in the first wearing state, the cooling material storage unit contacts at least one of the user's back and waist, and in the second wearing state, the cooling material storage unit contacts the user's neck. This allows the user to selectively change the part of the body to be cooled depending on the wearing state of the cooling suit, thereby improving the convenience of the cooling suit.

[0035]

[14] When the cooling material storage section is a first cooling material storage section, it is preferable that a second cooling material storage section be further provided, and that in the first wearing state, the second cooling material storage section be in contact with the side of the user, and in the second wearing state, the second cooling material storage section be in contact with the chest of the user.

[0036] According to this configuration, in the first wearing state, the second cooling material storage section contacts the user's armpit, and in the second wearing state, the second cooling material storage section contacts the user's chest. This allows the user to selectively change the part of the body to be cooled depending on the wearing state of the cooling suit. This improves the convenience of the cooling suit.

[0037]

[15] It is preferable that the apparatus further includes a gas concentration measuring device, and the coolant is dry ice.

[0038] According to this configuration, the work equipment further includes a gas concentration measuring device, and the coolant is dry ice. Dry ice has superior cooling performance compared to ice. However, dry ice generates carbon dioxide gas. Therefore, the gas concentration measuring device monitors at least one of the carbon dioxide concentration and the oxygen concentration in the atmosphere around the user. Therefore, the user can directly or indirectly grasp the oxygen concentration in the atmosphere around him / her, improving the safety of the user wearing the work uniform.

[0039]

[16] A cooling suit to be worn by a user, the cooling suit defining the side of the user's head as the upper side when the user is standing and wearing the cooling suit, the cooling suit comprising a clothing body and a cooling material storage section capable of storing a cooling material and attached to the clothing body, the clothing body having a back body and armholes, the cooling material storage section having a back body cooling material storage section provided on the back body, the armholes having a first armhole through which one arm of the user passes when the cooling suit is worn by the user, and a second armhole located on the opposite side of the first armhole and through which the other arm of the user passes, The cooling suit can be selected by the user between a first wearing state and a second wearing state, and in the first wearing state, the user's right arm passes through the first sleeve opening, the user's left arm passes through the second sleeve opening, and the back body is positioned on the user's back, and in the second wearing state, the user's left arm passes through the first sleeve opening, the user's right arm passes through the second sleeve opening, and the back body is positioned on the user's back, and the upper end of the rear body cooling material storage section in the second wearing state is positioned higher than the upper end of the rear body cooling material storage section in the first wearing state.

[0040] According to this configuration, the upper end of the rear body cooling material storage compartment in the second wearing state is positioned higher than the upper end of the rear body cooling material storage compartment in the first wearing state. The user can switch between the first and second wearing states while using the cooling suit. This allows cooling of other body parts before a certain body part becomes overcooled and causes the user X's discomfort. This allows the user to continue using the cooling suit comfortably and prevents the user from discontinuing use of the cooling suit before the cooling material's lifespan expires due to a deterioration in comfort. This ultimately improves the cooling suit's cooling duration.

[0041]

[17] It is preferable that the garment has a pocket portion attached to the main garment body and capable of storing the cooling material, the main garment body has a front body, the cooling material storage portion has a front body cooling material storage portion provided on the front body, the pocket portion is provided on the front body, and in the first wearing state, the front body cooling material storage portion is located to the side of the user, and in the second wearing state, the pocket portion is located to the side of the user.

[0042] According to this configuration, in the first wearing state, the front body cooling material storage section is located to the side of the user, and in the second wearing state, the pocket section is located to the side of the user. Therefore, whether the user selects the first or second wearing state, at least one of the front body cooling material storage section and the pocket section is located to the side of the user. Therefore, the user's body can be cooled from a side other than the back. This ultimately improves the cooling performance of the cooling suit.

[0043] The cooling system of the present disclosure

[18] A cooling suit that uses dry ice as a coolant and is worn by a user, and a dry ice generating device that generates the dry ice from liquefied carbon dioxide gas supplied from a cylinder, wherein the cooling suit has a suit body, a coolant storage section that is capable of storing the dry ice and is attached to the suit body, and an insulating section that is attached to the suit body, and the insulating section is interposed between the suit body and the coolant storage section, and when the cooling suit is worn by the user, the coolant storage section is positioned closer to the user than the insulating section.

[0044] This configuration includes a cooling suit that uses dry ice as a coolant and is worn by a user, and a dry ice generator that generates the dry ice from liquefied carbon dioxide gas supplied from a cylinder. By using the dry ice generator, the user can generate the amount of dry ice needed for the day of work. Therefore, by using the cooling system 100, the user can efficiently use the cooling suit.

[0045] Furthermore, with this configuration, when the cooling suit is worn by a user, the cooling material storage compartment is located closer to the user than the insulating material. This allows the cooling material stored in the cooling material storage compartment to cool the user's body. Furthermore, the insulating section is interposed between the clothing body and the cooling material storage compartment. This reduces heat conduction from the clothing body to the cooling material, and reduces the impact of heat from the clothing body on the cooling material. This therefore improves the cooling duration of the cooling suit.

[0046] [Details of the embodiments of the present disclosure] Specific examples of the cooling suit and cooling system of the present disclosure are described below with reference to the drawings. The present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims. For ease of explanation, some components may be exaggerated or simplified in the drawings. The dimensional ratios of each part may differ between drawings. In the following description of the drawings, the same or similar parts may be denoted by the same or similar reference numerals. In this specification, "parallel" and "orthogonal" do not only refer to strictly parallel or orthogonal relationships, but also include roughly parallel or orthogonal relationships within the scope of the present embodiment.

[0047] [First embodiment] An overview of the first embodiment will now be described. Fig. 1 is a front view of a cooling suit 10 according to the first embodiment. Fig. 2 is a front view of the cooling suit 10 according to the first embodiment with the front body part open. Fig. 3 is a partially enlarged view showing the storage of the cooling material 24 in the cooling suit 10 according to the first embodiment.

[0048] As shown in Figures 1 and 2, the cooling suit 10 comprises a clothing body 2, a cooling material storage section 4 capable of storing a cooling material 24, an insulating section 6 interposed between the clothing body 2 and the cooling material storage section 4, and a pocket section 12.

[0049] The garment body 2 is formed in a vest shape. The garment body 2 is made of a fabric containing nylon and polyurethane, and a fabric containing polyester and cotton. The garment body 2 has greater stretchability than the insulating part 6. The garment body 2 is flame retardant. The garment body 2 has piped edges. The fabric of the piped part of the garment body 2 contains 80% to 90% nylon and 10% to 20% polyurethane. The piped part of the garment body 2 is stretchable. The garment body 2 may be formed by combining fabrics of different compositions so that the stretchability varies depending on the part of the body that it comes into contact with.

[0050] The garment body 2 has a front body 5, a back body 9, armholes 30, and a pair of belts 26. The front body 5 has a first front body 5a extending from one end of the back body 9, and a second front body 5b extending from the other end of the back body 9.

[0051] The sleeve cutting 30 has a first sleeve cutting 30a which is a through hole surrounded by the first front body part 5a and the back body part 9, and a second sleeve cutting 30b which is a through hole surrounded by the second front body part 5b and the back body part 9. The arms of the user X can pass through the first sleeve cutting 30a and the second sleeve cutting 30b.

[0052] One of the pair of belts 26 is attached to the first front body piece 5a. The other of the pair of belts 26 is attached to the second front body piece 5b. Each of the pair of belts 26 has a belt-shaped member 32 and a belt connection part 34.

[0053] The belt-shaped member 32 is a belt-shaped member made of a synthetic fiber such as nylon. The belt-shaped member 32 has one end and another end opposite the one end in the longitudinal direction. One end of the belt-shaped member 32 is sewn to the front body 5 of the garment main body 2. A belt connection part 34 is attached to the belt-shaped member 32, for example, closer to the other end of the belt-shaped member 32 than the one end of the belt-shaped member 32.

[0054] The belt connection parts 34 of the pair of belt parts 26 can be connected to each other. The connected pair of belt connection parts 34 can be released from the connected state. By connecting the belt connection parts 34 of the pair of belt parts 26, the cooling suit 10 can be fixed to the user X. By releasing the connected state of the connected pair of belt connection parts 34, the user X can easily take off the cooling suit 10.

[0055] The pair of belt connection parts 34 are, for example, side release buckles. The position of at least one of the pair of belt connection parts 34 can be adjusted relative to the belt-shaped member 32, and the length from the belt connection part 34 to one end of the belt-shaped member 32 can be adjusted. In other words, the force with which the pair of belt parts 26 fasten the cooling suit 10 to the user X can be adjusted.

[0056] As shown in FIG. 4(a), the first wearing state of the cooling suit 10 is when the user X puts his / her right arm through the first sleeve opening 30a, the user X puts his / her left arm through the second sleeve opening 30b, and the back body 9 is positioned at the user X's back. As shown in FIG. 4(b), the second wearing state is when the user X puts his / her left arm through the first sleeve opening 30a, the user X puts his / her right arm through the second sleeve opening 30b, and the back body 9 is positioned at the user X's back. When the user X is standing and wearing the cooling suit 10, the side of the user X's head is defined as the upper side of the cooling suit 10. The second wearing state is when the cooling suit 10 is worn upside down compared to the first wearing state. Hereinafter, when a description is given assuming the cooling suit 10 is worn in a worn state, the first wearing state will be assumed unless otherwise specified.

[0057] As shown in Fig. 2, the cooling material storage section 4 has an opening 22, an opening / closing structure 23 that can open and close at least a portion of the opening 22, and a surface layer 42. The opening / closing structure 23 is, for example, a linear fastener. The cooling material storage section 4 has a back body cooling material storage section 4A that is arranged in the back body section 9, and a front body cooling material storage section 4B that is arranged in the front body section 5. The surface layer 42 comes into contact with the body of the user X when the cooling suit 10 is worn by the user X. The surface layer 42 is, for example, mesh-like.

A heat insulating material 6 is interposed between the back body cooling material storage section 4A and the back body 9. The back body cooling material storage section 4A, the back body 9, and the heat insulating material 6 are aligned along a first direction in which the back body cooling material storage section 4A, the back body 9, and the heat insulating material 6 overlap.

[0059] The back body cooling material storage section 4A is, for example, rectangular. The back body cooling material storage section 4A is stretchable. The back body cooling material storage section 4A is formed into a pocket shape with a hollow space by sewing the edges of a mesh-like fiber sheet to the back body 9. The mesh-like fiber sheet fabric that makes up the back body cooling material storage section 4A contains 80% to 90% nylon and 10% to 20% polyurethane. The back body surface layer 42A is part of the mesh-like fiber sheet that forms the back body cooling material storage section 4A. The back body surface layer 42A is stretchable. When the cooling suit 10 is worn by the user X, the back body surface layer 42A faces the body of the user X.

[0060] The back body opening 22A is provided on one of the sides that make up the rectangle of the back body cooling material storage section 4A. The back body opening 22A opens the hollow space of the back body cooling material storage section 4A toward the outside space of the back body cooling material storage section 4A. The back body opening 22A allows the cooling material 24 to be put in and taken out of the back body cooling material storage section 4A.

[0061] As shown in FIG. 3, the back body opening and closing structure 23A is a structure for opening and closing at least a portion of the back body opening 22A of the back body cooling material storage section 4A. The back body opening and closing structure 23A is a structure for opening and closing the hollow space formed by the back body cooling material storage section 4A. The back body opening and closing structure 23A is, for example, a linear fastener. By opening the back body opening and closing structure 23A, the user X can store the cooling material 24 in the back body cooling material storage section 4A. By closing the back body opening and closing structure 23A, the user X can prevent the cooling material 24 from falling out of the back body cooling material storage section 4A.

[0062] 2, in this embodiment, a plurality of rear body cooling material storage sections 4A are provided, including, for example, a first rear body cooling material storage section 4a, a second rear body cooling material storage section 4b, a third rear body cooling material storage section 4c, and a fourth rear body cooling material storage section 4d.

[0063] The first back body cooling material storage section 4a and the second back body cooling material storage section 4b are arranged side by side in a second direction perpendicular to the first direction. The first back body cooling material storage section 4a and the second back body cooling material storage section 4b are arranged between the first armhole 30a and the second armhole 30b. The first back body cooling material storage section 4a and the second back body cooling material storage section 4b are arranged side by side in the direction in which the first armhole 30a and the second armhole 30b are arranged side by side. The first back body cooling material storage section 4a is located closer to the first armhole 30a than the second back body cooling material storage section 4b.

The front body opening 22B has a front body opening / closing structure 23B that opens and closes the hollow space formed by the front body coolant storage section 4B. The front body opening 22B opens the hollow space of the front body coolant storage section 4B toward the space outside the front body coolant storage section 4B. The front body opening 22B allows coolant 24 to be put in and taken out of the front body coolant storage section 4B.

[0072] The front body opening and closing structure 23B is a structure for opening and closing at least a portion of the front body opening 22B of the front body cooling material storage section 4B. The front body opening and closing structure 23B is a structure for opening and closing the hollow space formed by the front body cooling material storage section 4B. The front body opening and closing structure 23B is, for example, a linear fastener. By opening the front body opening and closing structure 23B, the user X can store the cooling material 24 in the front body cooling material storage section 4B. By closing the front body opening and closing structure 23B, the user X can prevent the cooling material 24 from falling out of the front body cooling material storage section 4B.

[0073] In this embodiment, a plurality of front body coolant storage sections 4B are provided, including, for example, a first front body coolant storage section 4e arranged in the first front body section 5a and a second front body coolant storage section 4f arranged in the second front body section 5b.

[0075] The pocket portion 12 is provided in the front body 5. The pocket portion 12 has a pocket opening 22C and a pocket surface layer 42C located on the side of the user X's body. The pocket portion 12 is rectangular. The pocket portion 12 is stretchable. The pocket portion 12 is formed by sewing three edges of a rectangular sheet to the front body 5. The sheet forming the pocket portion 12 may be made of a fabric that is more stretchable than the fabric of the other parts of the garment body 2. The pocket portion 12 can house a bag (not shown) that contains a separately provided cooling material 24. The pocket surface layer 42C is part of the sheet forming the pocket portion 12. The pocket surface layer 42C is stretchable. The pocket surface layer 42C faces the body of the user X when the cooling garment 10 is worn by the user X.

[0076] The pocket 12 has a first pocket 12A provided in the first front body portion 5a and a second pocket 12B provided in the second front body portion 5b. When the front body portion 5 of the cooling suit 10 is open, the back body cooling material storage portion 4A is located between the first pocket portion 12A and the second pocket portion 12B. An armhole 30 is located between the first pocket portion 12A and the second pocket portion 12B.

[0077] The heat insulating part 6 is a member in which an aluminum film is laminated onto a urethane foam sheet. The heat insulating part 6 is interposed between the garment main body 2 and the cooling material storage part 4. The heat insulating part 6 is sewn to the garment main body 2. The heat insulating part 6 may also be welded to the garment main body 2. The heat insulating part 6 may be placed between one cooling material storage part 4 and the garment main body 2, or may be placed between multiple cooling material storage parts 4 and the garment main body 2.

[0078] The heat insulating section 6 has a first heat insulating section 6a, a second heat insulating section 6b, and a third heat insulating section 6c. The first heat insulating section 6a, the second heat insulating section 6b, and the third heat insulating section 6c may be made of the same material or different materials.

[0079] The first insulating section 6a is attached to the back body 9. The first insulating section 6a is interposed between the back body 9 and the back body cooling material storage section 4A. The first insulating section 6a has a first separate insulating section 60a which is a first region, and a second separate insulating section 60b which is a second region separated from the first separate insulating section 60a.

[0080] The first separate heat insulating section 60a extends along the third direction. The first separate heat insulating section 60a extends along the up-down direction. The first separate heat insulating section 60a straddles the first back body cooling material storage section 4a and the third back body cooling material storage section 4c. The first separate heat insulating section 60a has less stretchability than the garment body 2. The first separate heat insulating section 60a has less stretchability than the back body 9.

[0081] The second separate heat insulating section 60b extends along the third direction. The second separate heat insulating section 60b extends along the up-down direction. The second separate heat insulating section 60b straddles the second back body cooling material storage section 4b and the fourth back body cooling material storage section 4d. The second separate heat insulating section 60a has less stretchability than the garment body 2. The second separate heat insulating section 60b has less stretchability than the back body 9.

[0082] The first separate heat insulation section 60a and the second separate heat insulation section 60b are spaced apart from each other in the direction in which the first rear body coolant storage section 4a and the second rear body coolant storage section 4b are aligned. The first separate heat insulation section 60a and the second separate heat insulation section 60b are spaced apart from each other in the second direction. The first separate heat insulation section 60a and the second separate heat insulation section 60b may be made of the same material or different materials.

[0083] The second insulating part 6b is attached to the first front body 5a. The second insulating part 6b is interposed between the first front body 5a and the first front body coolant storage part 4e. The second insulating part 6b is spaced apart from the first insulating part 6a.

[0084] The third insulating portion 6c is attached to the second front body 5b. The third insulating portion 6c is interposed between the second front body 5b and the second front body coolant storage portion 4f. The third insulating portion 6c is spaced apart from the first insulating portion 6a. The third insulating portion 6c is spaced apart from the second insulating portion 6b.

[0085] The cooling material 24 is, for example, dry ice. The cooling material 24 may be any material that can cool the body of the user X, and may be, other than dry ice, ice, water, or a cooling agent containing a highly water-absorbent resin.

[0086] The cooling suit 10 having the above-described configuration is used as follows. As shown in FIG. 3 , user X opens the opening 22 of the cooling material storage section 4, inserts the cooling material 24, and closes the opening 22. User X puts on the cooling suit 10. When user X puts on the cooling suit 10, the cooling material storage section 4 is placed on the user X's side. The cooling material 24 cools the air around the cooling material 24 and the cooling material storage section 4. The air cooled by the cooling material 24 exits the cooling material storage section 4 through the surface layer 42 of the cooling material storage section 4. Furthermore, the cooling material storage section 4 cooled by the cooling material 24 cools the air around the cooling material storage section 4. In addition, the cooled cooling material storage section 4 cools user X when it comes into contact with the user X's body. In this way, the cooling suit 10 can cool the user X's body. The same applies when the cooling material 24 is stored in the pocket section 12.

[0087] In this specification, "contact" does not only mean strictly direct contact, but also includes indirect contact within the scope of the effects of this embodiment. For example, it also includes a case where an intervening object is present between the coolant storage unit 4 and the body of user X, and the coolant storage unit 4 pushes the intervening object toward the body of user X.

[0088] As shown in Figures 4(a) and 4(b), when wearing the cooling suit 10, the user X can select between a first wearing state and a second wearing state. The parts of each of the cooling material storage sections 4 and each of the pocket sections 12 that come into contact with the user X's body differ between the first wearing state and the second wearing state. By selecting between the first wearing state and the second wearing state, the user X can adjust the part of the body that is to be cooled.

[0089] As shown in FIG. 4(a), the back body cooling material storage section 4A is placed on the back of the user X in the first wearing state. The back body cooling material storage section 4A contacts at least one of the back and waist of the user X in the first wearing state. The first back body cooling material storage section 4a contacts the upper right part of the back of the user X in the first wearing state. The second back body cooling material storage section 4b contacts the upper left part of the back of the user X in the first wearing state. The third back body cooling material storage section 4c contacts the lower right part of the back of the user X in the first wearing state. The fourth back body cooling material storage section 4d contacts the lower left part of the back of the user X in the first wearing state.

[0090] The front body cooling material storage section 4B is positioned on the side of the user X in the first wearing state. The front body cooling material storage section 4B contacts the side of the chest of the user X in the first wearing state. The front body cooling material storage section 4B contacts the side of the user X in the first wearing state. The first front body cooling material storage section 4e contacts the right side of the first user X in the first wearing state. The second front body cooling material storage section 4f contacts the left side of the user X in the first wearing state.

[0091] In the first wearing state, the pocket portion 12 comes into contact with the chest of the user X. In the first wearing state, the first pocket portion 12A comes into contact with the right chest of the user X. In the first wearing state, the second pocket portion 12B comes into contact with the left chest of the user X.

[0092] As shown in FIG. 4(b), the back body cooling material storage section 4A is placed on the back of the user X in the second wearing state. The back body cooling material storage section 4A contacts at least one of the back and neck of the user X in the second wearing state. The first back body cooling material storage section 4a contacts the lower left part of the back of the user X in the second wearing state. The second back body cooling material storage section 4b contacts the lower right part of the back of the user X in the second wearing state. The third back body cooling material storage section 4c contacts at least one of the upper left part of the back and neck of the user X in the second wearing state. The fourth back body cooling material storage section 4d contacts at least one of the upper right part of the back and neck of the user X in the second wearing state.

[0093] When user X is standing and wearing the cooling suit 10, if the side of user X's head is defined as the upper side, the third back body cooling material storage section 4c and the fourth back body cooling material storage section 4d in the second wearing state are positioned higher than the third back body cooling material storage section 4c and the fourth back body cooling material storage section 4d in the first wearing state. The first back body cooling material storage section 4a and the second back body cooling material storage section 4b in the first wearing state are positioned higher than the first back body cooling material storage section 4a and the second back body cooling material storage section 4b in the second wearing state. The upper ends of the third back body cooling material storage section 4c and the fourth back body cooling material storage section 4d in the second wearing state are positioned higher than the upper ends of the first back body cooling material storage section 4a and the second back body cooling material storage section 4b in the first wearing state.

[0094] The front body cooling material storage section 4B contacts the chest of the user X in the second wearing state. The first front body cooling material storage section 4e contacts the left chest of the user X in the second wearing state. The second front body cooling material storage section 4f contacts the right chest of the user X in the second wearing state.

[0095] The pocket 12 contacts the armpit of the user X in the second wearing state. The pocket 12A contacts the left armpit of the user X in the second wearing state. The second pocket 12B contacts the right armpit of the user X in the first wearing state.

[0096] The user X can adjust the coolant 24 stored in the coolant storage section 4 and the pocket section 12 as needed. The user X may omit storing the coolant 24 in part of the coolant storage section 4 and the pocket section 12. The user X may use a combination of ice, water, and a cooling agent containing a highly water-absorbent resin, in addition to dry ice, as the coolant 24.

[0097] The operation and effects of the first embodiment will be described. (1) A cooling suit 10 to be worn by a user X, comprising a clothing body 2, a cooling material storage section 4 capable of storing a cooling material 24 and attached to the clothing body 2, and a heat insulating section 6 attached to the clothing body 2. The heat insulating section 6 is interposed between the clothing body 2 and the cooling material storage section 4. When the cooling suit 10 is worn by the user X, the cooling material storage section 4 is positioned closer to the user X than the heat insulating section 6.

[0098] According to this configuration, when the cooling suit 10 is worn by the user X, the cooling material storage section 4 is positioned closer to the user X than the heat insulating material 6. Therefore, the body of the user X can be cooled by the cooling material 24 stored in the cooling material storage section 4. Furthermore, the heat insulating section 6 is interposed between the garment body 2 and the cooling material storage section 4. This prevents heat from being transferred from the garment body 2 to the cooling material 24, and reduces the influence of heat on the cooling material 24 from the garment body 2 side. This improves the cooling duration of the cooling suit 10.

[0099] (2) When the cooling suit 10 is worn by the user X, the cooling material storage section 4 has a surface layer 42 that faces the user X. The surface layer 42 is mesh-like.

[0100] According to this configuration, the surface layer 42 of the coolant storage unit 4 is mesh-shaped. Because the surface layer 42 of the coolant storage unit 4 is mesh-shaped, the surface layer 42 of the coolant storage unit 4 allows air inside the coolant storage unit 4 that has been cooled by the coolant 24 to easily pass through. This improves the cooling performance of the cooling suit 10.

[0101] (3) The coolant storage section 4 preferably has an opening 22 through which the coolant 24 can be put in and taken out, and an opening / closing structure 23 configured to be able to open and close at least a portion of the opening 22.

[0102] According to this configuration, the coolant storage section 4 has an opening / closing structure 23 configured to be able to open and close at least a portion of the opening 22. Therefore, when storing the coolant 24 in the coolant storage section 4, the opening 22 is opened by the opening / closing structure 23, and the coolant 24 can be stored in the coolant storage section 4. Furthermore, after the coolant 24 has been stored in the coolant storage section 4, the opening 22 is closed by the opening / closing structure 23, which prevents the coolant 24 from falling out of the opening 22. This improves the convenience of the cooling suit 10.

[0103] (4) The opening and closing structure 23 is a wire zipper.

[0104] According to this configuration, the opening and closing structure 23 is a linear fastener. When the opening and closing structure 23 is a linear fastener, it is possible to prevent the user X from touching the opening and closing structure 23 and unintentionally opening the opening 22 when putting on the cooling suit 10, compared to when the opening and closing structure 23 is a hook-and-loop fastener or buttons. This makes it possible to prevent the cooling material 24 from falling out of the cooling suit 10. Furthermore, when the opening and closing structure 23 is a linear fastener, the durability of the opening and closing structure is improved compared to when the opening and closing structure 23 is a hook-and-loop fastener.

[0105] (5) The garment body 2 has a back body 9, and the cooling material storage section 4 has a back body cooling material storage section 4A provided in the back body 9.

[0106] According to this configuration, the cooling material storage section 4 has a back body cooling material storage section 4A provided in the back body 9. This allows the body of the user X to be cooled from the back side of the user X, and does not restrict the range of motion of the user X's arms. This prevents a decrease in the workability of the user X wearing the cooling suit 10.

[0107] (6) The rear body cooling material storage section 4A has a first rear body cooling material storage section 4a and a second rear body cooling material storage section 4b.

[0108] According to this configuration, the back body cooling material storage section 4A has a first back body cooling material storage section 4a and a second back body cooling material storage section 4b. Therefore, the user X can selectively store the cooling material 24 in the back body cooling material storage section 4A that corresponds to the part of their body that they wish to cool. This allows the user X to more flexibly adjust the cooling performance of the cooling suit 10, improving the convenience of the cooling suit 10.

[0109] (7) The rear body opening 22A of the first rear body cooling material storage section 4a faces the opposite side to the second rear body cooling material storage section 4b, and the rear body opening 22A of the second rear body cooling material storage section 4b faces the opposite side to the first rear body cooling material storage section 4a.

[0110] According to this configuration, the back opening 22A of the first back body cooling material storage section 4a faces away from the second back body cooling material storage section 4b, and the back opening 22A of the second back body cooling material storage section 4b faces away from the first back body cooling material storage section 4a. When the user X stores the cooling material 24 in the first back body cooling material storage section 4a, the first back body cooling material storage section 4a expands by the amount of the cooling material 24. Because the back opening 22A of the second back body cooling material storage section 4b faces away from the first back body cooling material storage section 4a, the user X can store the cooling material 24 in the second back body cooling material storage section 4b more easily than if it were facing the first back body cooling material storage section 4a. This improves the convenience of the cooling suit 10.

[0111] (8) The heat insulating part 6 has a first region 60a and a second region 60b spaced apart from the first region 60a. The garment body 2 has greater stretchability than the first region 60a of the heat insulating part 6 and greater stretchability than the second region 60b of the heat insulating part 6.

[0112] According to this configuration, the garment body 2 has greater stretchability than the first region 60a of the thermal insulation section 6 and greater stretchability than the second region 60b of the thermal insulation section 6. Therefore, in the region where the thermal insulation section 6 is not present, the garment body 2 stretches, which can prevent a decrease in the stretchability of the cooling suit 10. Therefore, a decrease in the comfort of the user X wearing the cooling suit 10 can be prevented.

[0113] (9) The heat insulating section 6 has a first separate heat insulating section 60a and a second separate heat insulating section 60b separated from the first separate heat insulating section 60a. The first separate heat insulating section 60a is interposed between the first rear body coolant storage section 4a and the rear body 9. The second separate heat insulating section 60b is interposed between the second rear body coolant storage section 4b and the rear body 9. The back body 9 has greater stretchability than the first separate heat insulating section 60a and also has greater stretchability than the second separate heat insulating section 60b.

[0114] With this configuration, the back body 9 has greater stretchability than the first separate insulation section 60a and the second separate insulation section 60b. Therefore, in areas where the first separate insulation section 60a and the second separate insulation section 60b are not present, the back body 9 stretches, thereby preventing a decrease in the stretchability of the cooling suit 10. Therefore, a decrease in the comfort of the user X wearing the cooling suit 10 can be prevented.

[0115] (10) The garment body 2 has sleeve openings 30. When the cooling suit 10 is worn by a user X, the sleeve opening 30 has a first sleeve opening 30a through which one arm of the user X passes, and a second sleeve opening 30b that is located on the opposite side of the first sleeve opening 30a and through which the other arm of the user X passes. The first separate insulation portion 60a and the second separate insulation portion 60b are aligned in the same direction as the first sleeve opening 30a and the second sleeve opening 30b in a front view.

[0116] According to this configuration, the first and second separate insulation sections 60a and 60b are aligned in the same direction as the first and second armholes 30a and 30b in a front view. Therefore, in the back body 9, the first and second separate insulation sections 60a and 60b are spaced apart in the same direction as the first and second armholes 30a and 30b. That is, when a user X wearing the cooling suit 10 stretches their arms forward, the first and second separate insulation sections 60a and 60b are spaced apart in the same direction as the back body 9 stretches. This prevents restriction of the range of motion of the user X's arms and prevents a decrease in the user X's workability while wearing the cooling suit 10.

[0117] (11) The garment body 2 preferably has a front body 5, and the cooling material storage section 4 preferably has a front body cooling material storage section 4B provided in the front body 5.

[0118] According to this configuration, the cooling material storage section 4 has a front body cooling material storage section 4B provided in the front body 5. This allows the body of the user X to be cooled from sides other than the back, thereby improving the cooling performance of the cooling suit 10.

[0119] (12) When the cooling suit 10 is worn by a user X, the cooling material storage section 4 contacts the side of the user X and the back cooling material storage section 4A contacts the user's back, and the front surface layer 42B of the front cooling material storage section 4B is thicker than the back surface layer 42A of the back cooling material storage section 4A.

[0120] According to this configuration, the front body surface layer 42B of the front body cooling material storage section 4B is thicker than the back body surface layer 42A of the back body cooling material storage section 4A. Because the armpits have a higher blood flow rate than the back, the body is more efficiently cooled. However, if the armpits and back are cooled with the same cooling material 24, some users X of the cooling suit 10 may feel that their armpits are overcooled. However, changing the type of cooling material 24 for each cooling target is undesirable from the perspective of convenience for the user X of the cooling suit 10. By making the front body surface layer 42B of the front body cooling material storage section 4B thicker than the back body surface layer 42A of the back body cooling material storage section 4A, the user X does not need to select the type of cooling material depending on the degree of cooling of their body. This improves the convenience of the cooling suit 10.

[0121] (13) When the cooling suit 10 is worn by the user X, the user X can select between a first wearing state and a second wearing state of the cooling suit 10. In the first wearing state, the cooling material storage unit 4 contacts at least one of the back and waist of the user X, and in the second wearing state, the cooling material storage unit 4 contacts the neck of the user X.

[0122] According to this configuration, in the first wearing state, the cooling material storage unit 4 contacts at least one of the back and waist of the user X, and in the second wearing state, the cooling material storage unit 4 contacts the neck of the user X. The user X can switch between the first and second wearing states while using the cooling suit 10. Therefore, by switching the wearing state, a different body part can be cooled before the user X experiences discomfort due to excessive cooling of a certain body part. This allows the user X to continue wearing the cooling suit 10 comfortably, and prevents the user X from discontinuing use of the cooling suit 10 before the life of the cooling material 24 expires due to a deterioration in comfort. Consequently, the cooling duration of the cooling suit 10 can be improved. Furthermore, the user X can selectively change the body part to be cooled depending on the wearing state of the cooling suit 10. This improves the convenience of the cooling suit 10.

[0123] (14) When the cooling material storage section 4 is the first cooling material storage section 4, the device further includes a second cooling material storage section 4. In the first wearing state, the second cooling material storage section 4 contacts the side of the user X. In the second wearing state, the second cooling material storage section 4 contacts the chest of the user X.

[0124] According to this configuration, in the first wearing state, the second cooling material storage section 4 is located at the side of the user X, and in the second wearing state, the second cooling material storage section 4 is located on the user X's chest. The user X can switch between the first and second wearing states while using the cooling suit 10. Therefore, by switching the wearing state, a different body part can be cooled before the user X experiences discomfort due to excessive cooling of a certain body part. This allows the user X to continue wearing the cooling suit 10 comfortably, and prevents the user X from discontinuing use of the cooling suit 10 before the life of the cooling material 24 expires due to a deterioration in comfort. This ultimately improves the cooling duration of the cooling suit 10. Furthermore, the user X can selectively change the body part to be cooled depending on the wearing state of the cooling suit 10. This improves the convenience of the cooling suit 10.

[0125] (15) A cooling suit 10 to be worn by a user X, wherein the side of the user X's head when the user X is standing and wearing the cooling suit 10 is defined as the upper side of the cooling suit 10. The cooling suit 10 comprises a garment main body 2 and a cooling material storage section 4 attached to the garment main body 2 and capable of storing a cooling material 24. The garment main body 2 has a back body 9 and armholes 30. The cooling material storage section 4 has a back body cooling material storage section 4A provided in the back body 9. The armholes 30 have a first armhole 30a through which one arm of the user X passes when the cooling suit 10 is worn by the user X, and a second armhole 30b located on the opposite side of the first armhole 30a and through which the other arm of the user X passes. When the cooling suit 10 is worn by the user X, the user X can select between a first wearing state and a second wearing state of the cooling suit 10. In the first wearing state, the right arm of the user X passes through the first sleeve opening 30a, and the left arm of the user X passes through the second sleeve opening 30b, and the back body 9 is located on the back of the user X. In the second wearing state, the left arm of the user X passes through the first sleeve opening 30a, and the right arm of the user X passes through the second sleeve opening 30b, and the back body 9 is located on the back of the user X. The upper end of the back body cooling material storage section 4A in the second wearing state is located higher than the upper end of the back body cooling material storage section 4A in the first wearing state.

[0126] According to this configuration, the upper end of the rear body cooling material storage section 4A in the second wearing state is positioned higher than the upper end of the rear body cooling material storage section 4A in the first wearing state. The user X can switch between the first and second wearing states while using the cooling suit 10. Therefore, by switching the wearing state, a different body part can be cooled before a certain body part becomes overcooled and the user X begins to feel uncomfortable. This allows the user X to continue using the cooling suit 10 comfortably, preventing the user X from discontinuing use of the cooling suit 10 before the life of the cooling material 24 expires due to a deterioration in comfort. Consequently, the cooling duration of the cooling suit 10 can be improved. Furthermore, the user X can selectively change the body part to be cooled depending on the wearing state of the cooling suit 10. This improves the convenience of the cooling suit 10.

[0127] (16) The garment has a pocket 12 attached to the garment body 2 and capable of storing a cooling material 24. The garment body 2 has a front body 5, the cooling material storage section 4 has a front body cooling material storage section 4B provided in the front body 5, the pocket 12 is provided in the front body 5, and it is preferable that in the first wearing state, the front body cooling material storage section 4B is positioned to the side of the user X, and in the second wearing state, the pocket 12 is positioned to the side of the user X.

[0128] According to this configuration, in the first wearing state, the front body cooling material storage section 4B is arranged on the side of the user X, and in the second wearing state, the pocket section 12 is arranged on the side of the user X. Therefore, regardless of whether the user X selects the first wearing state or the second wearing state, at least one of the front body cooling material storage section 4B and the pocket section 12 is arranged on the side of the user X. Therefore, the body of the user X can be cooled from the side other than the back, which in turn improves the cooling performance of the cooling suit 10.

[0129] (Modification 1 of the first embodiment) Modification 1 of the first embodiment will be described. Fig. 5 is a front view of the cooling suit 10 of Modification 1 of the first embodiment. The cooling suit 10 differs from the cooling suit 10 of the first embodiment in that it further includes a gas concentration measuring device 8.

[0130] The gas concentration measuring instrument 8 is, for example, an oxygen concentration meter. The oxygen concentration meter can measure the oxygen concentration in the atmosphere. The gas concentration measuring instrument 8 displays the measured oxygen concentration value and issues an alarm if the measured value falls below a set value.

[0131] The gas concentration measuring device 8 is provided somewhere on the garment body 2. The gas concentration measuring device 8 is stored in a storage space provided near the mouth and nose of the user X, such as on the chest, shoulders, or back, where it is not directly exposed to exhaled air. The portion of the garment body 2 corresponding to the pocket 12 may be made mesh-like or otherwise made breathable so that the gas concentration measuring device 8 can be stored in the pocket 12. In this case, a stretchy fabric may be used in this portion to prevent pressure on the chest of the user X.

[0132] The user X performs work wearing the cooling suit 10 containing dry ice as the coolant 24. The gas concentration measuring device 8 issues a warning sound to alert the user X if the oxygen concentration falls below a set value.

[0133] In the above description of the first modification of the first embodiment, the gas concentration measuring instrument 8 is an oxygen concentration meter, but it may be a carbon dioxide concentration meter or a gas concentration measuring instrument that can measure oxygen concentration and carbon dioxide concentration. The carbon dioxide concentration meter may be configured to emit a warning sound when the measured carbon dioxide concentration exceeds a certain value.

[0134] The operation and effects of the first modification of the first embodiment will be described. (17) A gas concentration measuring device 8 is further provided, and the coolant 24 is dry ice.

[0135] According to this configuration, the workwear 10 further includes a gas concentration measuring device 8, and the coolant 24 is dry ice. Dry ice has superior cooling performance compared to ice. However, dry ice generates carbon dioxide gas. Therefore, the gas concentration measuring device 8 monitors at least one of the carbon dioxide concentration and the oxygen concentration in the atmosphere around the user X. Therefore, the user X can directly or indirectly detect a decrease in the oxygen concentration in the atmosphere around him / her, improving the safety of the user X wearing the workwear 10.

[0136] (Second embodiment) An overview of the second embodiment will be described. Fig. 6 is a configuration diagram of a cooling system 100 according to the second embodiment. The cooling system 100 according to the second embodiment differs from the first embodiment in that it further includes a dry ice production device 50. The cooling system 100 according to the second embodiment can use the cooling suit 10 described in the first embodiment or the cooling suit 10 described in the modified example of the first embodiment.

[0137] 6, the cooling system 100 includes the cooling suit 10 and a dry ice production device 50. The dry ice production device 50 may be of a stationary type or a portable type.

[0138] The dry ice production device 50 is a device that uses liquefied carbon dioxide gas as a raw material to produce dry ice, which is the coolant 24. The dry ice production device 50 is supplied with liquefied carbon dioxide gas from a cylinder 52 in which the liquefied carbon dioxide gas is stored.

[0139] The dry ice generator 50 may be one that generates plate-shaped dry ice, pellet-shaped dry ice, or dry ice of other shapes. Plate-shaped dry ice has a smaller surface area than pellet-shaped dry ice and therefore sublimes more slowly than pellet-shaped dry ice. Therefore, when plate-shaped dry ice is used in the cooling suit 10, the cooling duration of the cooling suit 10 is longer than when pellet-shaped dry ice is used. The amount of pellet-shaped dry ice stored in the cooling material storage section 4 of the cooling suit 10 can be adjusted more precisely than when plate-shaped dry ice is used. Therefore, when pellet-shaped dry ice is used in the cooling suit 10, it is easier to adjust the cooling performance of the cooling suit 10 than when plate-shaped dry ice is used.

[0140] The dry ice production device 50 is placed at or near the location where the user X works. The dry ice production device 50 is placed, for example, in a factory, an oil refinery, an office, or the like.

[0141] The cooling system 100 having the above configuration is used as follows. A dry ice production device 50 is placed in a factory where a user X of the cooling suit 10 works. The dry ice production device 50 is supplied with liquefied carbon dioxide gas from a cylinder 52 and produces dry ice as the coolant 24. The user X stores the produced dry ice in the coolant storage section 4 of the cooling suit 10. The user X works while wearing the cooling suit 10.

[0142] The operation and effects of the second embodiment will be described. (18) The cooling suit 10 uses dry ice as a coolant 24 and is worn by a user X, and includes a dry ice generator 50 that generates dry ice from liquefied carbon dioxide gas supplied from a cylinder 52. The cooling suit 10 has a main body 2, a coolant storage section 4 that is capable of storing dry ice and is attached to the main body 2, and a heat insulating section 6 that is attached to the main body 2. The heat insulating section 6 is interposed between the main body 2 and the coolant storage section 4, and when the cooling suit 10 is worn by a user, the coolant storage section 4 is positioned closer to the user X than the heat insulating section 6.

[0143] According to this configuration, the cooling suit 10 uses dry ice as a cooling material 24 and is worn by a user X, and includes a dry ice production device 50 that produces dry ice from liquefied carbon dioxide gas supplied from a cylinder 52.

[0144] If dry ice is used as the coolant 24, it must be transported and stored at low temperatures due to its sublimation properties, which raises concerns that long-term storage may be difficult. Furthermore, the amount of dry ice required as the coolant 24 may vary depending on the type of work performed by User X and the temperature on the day of work. Therefore, it is difficult for User X to prepare and store the amount of dry ice 24 expected to be required over a certain period of time.

[0145] On the other hand, liquefied carbon dioxide, which is the raw material for dry ice, the coolant 24, can be transported and stored relatively easily by filling and storing it in a cylinder 52. The liquefied carbon dioxide can be supplied from the cylinder 52 to the dry ice production device 50. Therefore, by using the dry ice production device 50, the user X can produce dry ice according to the amount of dry ice required on the day of work. Therefore, by using the cooling system 100, the user X can efficiently use the cooling suit 10.

[0146] Furthermore, with this configuration, when the cooling suit 10 is worn by the user X, the cooling material storage section 4 is positioned closer to the user X than the heat insulating material 6. Therefore, the body of the user X can be cooled by the cooling material 24 stored in the cooling material storage section 4. Furthermore, the heat insulating section 6 is interposed between the garment body 2 and the cooling material storage section 4. This prevents heat from being transferred from the garment body 2 to the cooling material 24, and reduces the influence of heat on the cooling material 24 from the garment body 2 side. This improves the cooling duration of the cooling suit 10.

[0147] <Example of change> The first embodiment, the modified example of the first embodiment, and the second embodiment can be modified and implemented as follows: The following modified examples can be implemented in appropriate combination with the first embodiment, the modified example of the first embodiment, and the second embodiment, as long as there is no technical contradiction.

The first region of the heat insulating section 6 and the second region of the heat insulating section 6 do not have to be composed of only the first heat insulating section 6a. The first region of the heat insulating section 6 and the second region of the heat insulating section 6 may be composed of the first heat insulating section 6a and the second heat insulating section 6b, or may be composed of the first heat insulating section 6a and the third heat insulating section 6c, or may be composed of the second heat insulating section 6b and the third heat insulating section 6c.
