Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the slacks of Patent Document 1, the feather-containing liner is arranged throughout the slacks and does not consider the sweating points of the wearer, so there may be stuffiness at the sweating points.

[0005] An object of the present invention is to provide undergarments that can ensure heat retention while suppressing stuffiness.

Means for Solving the Problems

[0006] One aspect of the present invention is an undergarment having a front body and a back body, where the front body has a right front body covering the front of the right leg and a left front body covering the front of the left leg, and has a pair of left and right first heat retention packs provided at positions corresponding to the inner thigh portions in each of the right front body and the left front body, where the pair of left and right first heat retention packs are arranged inside the width direction from the respective front center lines of the right front body and the left front body, to provide an undergarment.

[0009] Embodiments of the present invention will be described below with reference to the drawings.

[0010] Figure 1 is a front view of the bottom garment 1 according to one embodiment of the present invention, as seen from the front of the wearer. Figure 2 is a side view of the bottom garment 1 as seen from the side of the wearer. Figure 3 is a rear view of the bottom garment 1 as seen from the back of the wearer. Hereinafter, the top and bottom, left and right, and front and back of the bottom garment 1 will be determined based on the wearer standing upright. Furthermore, the direction from the outer surface in the thickness direction of the fabric toward the inside will be defined as the inner side, and the opposite direction will be defined as the outer side. The direction toward the outside in the width direction will be defined as the outside, and the direction toward the center in the width direction will be defined as the inside.

[0011] Referring to Figures 1-3, the trousers 1 are formed from, for example, woven and / or knitted fabric. The trousers 1 have at least a front panel 2 and a back panel 3. The front panel 2 and the back panel 3 represent the parts that cover the front and back of the wearer 9, respectively, and the front panel 2 and the back panel 3 are separated on both sides in the width direction. The pre-sewing patterns that make up the trousers 1 do not necessarily have to be formed to coincide with the division of the front panel and the back panel, the front panel and the back panel may include two or more patterns, or the front panel and the back panel may be formed integrally.

[0012] In this embodiment, the lower garment 1 is formed by sewing the front body 2 and the back body 3 together on the inside and outside in the width direction, thereby creating an inner thigh seam IL, which is the seam on the inside of the lower garment 1, and a side seam SL, which is the seam on the outside of the lower garment 1.

[0013] As shown in Figure 1, the front panel 2 has a left front panel 21 that covers the front of the wearer's left leg, a right front panel 22 that covers the front of the right leg, and front center lines CL1 of the left front panel 21 and the right front panel 22, respectively. As shown in Figure 3, the back panel 3 has a left back panel 31 that covers the back of the wearer's left leg, a right back panel 32 that covers the back of the right leg, and front center lines CL2 of the left back panel 31 and the front and rear panels 32, respectively.

[0014] In this specification, the waistline WL, hipline HL, thigh line CRL, body centerline CL, front centerline CL1, back centerline CL2, and knee line KL each conform to the definitions of JIS L011:2006 (Body Terminology for Clothing). As shown in Figure 4, the waistline WL is the intersection of the horizontal plane and the body surface at a point midway between the lowest end of the ribs and the ilium. The hipline HL is the intersection of the horizontal plane and the body surface at the posterior prominence of the buttocks, or the straight line connecting the left and right trochanter points (the uppermost edge of the greater trochanter of the femur (the large projection on the upper outer side of the femur)). The thigh line CRL is a horizontal straight line passing through a point at the height of the base of the legs (also called the crotch point CP). The body centerline CL is a straight line extending vertically, roughly coinciding with the wearer's centerline. The front center line CL1 is a straight line extending vertically through the point that bisects the widthwise crossover lines CRL of each left and right front body panel. The back center line CL2 is a straight line extending vertically through the point that bisects the widthwise crossover lines CRL of each left and right back body panel. The knee line KL is a horizontal straight line passing through the point at the height of the center of the kneecap. Body measurements are taken, for example, with the subject in an upright posture with both arms hanging naturally, knees extended, both heels together, and toes slightly apart. Alternatively, the above lines and points may be applied to the waistline WL, hip line HL, crossover line CRL, body center line CL, front center line CL1, back center line CL2, and knee line KL of a mannequin (mannequin manufactured by Nanairo Co., Ltd.: MD-20A (men's)) when the lower garment 1 is dressed on the mannequin.

[0015] As shown in Figures 1-3, the lower garment 1 further includes a front insulation pack (first insulation pack) 4 positioned on the front body 2 and rear insulation packs (second to fourth insulation packs) 5 positioned on the back body 3.

[0016] The front and rear insulation packs 4 and 5 are constructed by enclosing a core material in woven and / or knitted fabric. The front and rear insulation packs 4 and 5 are provided to enhance the heat retention of the lower garment 1.

[0017] The weave structure of the woven fabric wrapping the core material and the knitting structure of the knitted fabric are not particularly limited, and known weave structures and knitting structures can be adopted. Examples of the weave structure of the woven fabric include plain weave, twill weave, and satin weave. Examples of the knitting structure of the knitted fabric include plain knitting, rubber knitting, double-sided knitting, and half knitting. The size of the gaps formed in the woven fabric or knitted fabric (the gaps between the yarns constituting the woven fabric or knitted fabric) is less than 0.5 mm in terms of the equivalent diameter of a circle (preferably 0.2 mm or less, more preferably 0.1 mm or less). From the perspective of preventing the core material from falling off, it is preferable to use a high-density woven fabric or a high-density knitted fabric as the woven fabric and the knitted fabric.

[0018] The core material is provided to enhance the heat retention performance of each heat retention pack 4, 5. As the core material, for example, fiber masses such as down (feathers), feathers, cotton, and synthetic fibers can be used. The core material may be arranged between a plurality of woven fabrics or knitted fabrics, or a single woven fabric or knitted fabric may be folded back and arranged therebetween. In either case, the core material will be entirely surrounded by the woven fabric or knitted fabric.

[0019] Prior to the description of the arrangement of each heat retention pack 4, 5, the sweating points and thermosensory points of the wearer 9 will be described.

[0020] First, an experiment for investigating the sweating points will be described. In this experiment, the distribution of the sweating amount of the subject was measured to investigate the sweating points. More specifically, the sweating amount of each part of the lower body of the human body was measured. In this experiment, the sweating amount was measured for the front center line block extending vertically along the front center line CL1 in front of the right foot of the subject, the rear center line block extending vertically along the rear center line CL2 on the back of the right foot of the subject, the side line block extending vertically through the side line SL on the side of the subject and generally parallel to the front and rear center lines CL1, CL2, and the inner thigh line block extending vertically through the inner thigh line IL on the inner thigh surface of the subject and generally parallel to the front and rear center lines CL1, CL2 (see FIG. 4). For convenience of explanation, in this embodiment, the front and rear center lines CL1, CL2, the side line SL, and the inner thigh line IL of the lower garment 1 and the front and rear center lines, the side line, and the inner thigh line of the left and right legs of the subject are in corresponding positions, so the same reference numerals are used.

[0021] The method for measuring the distribution of sweat volume is the filter paper method. In this specification, the filter paper method involves attaching filter paper to the measurement points of subjects, who enter an artificial climate chamber. After the subject's sweat volume stabilizes, the difference in weight between the filter paper at 30 minutes (after the experiment) and the filter paper at the start of the experiment is measured as the amount of sweat. The environmental conditions were 35°C and 50% RH (artificial climate chamber). Ten male subjects in their 20s were tested, and measurements were taken at 32 locations on the right side of the lower body.

[0022] As shown in Figure 4, the above experiment revealed that, on the side, sweating was highest in the axillary region R1, from the hip line HL to the knee line KL. On the back, sweating was highest in the gluteal region R2, from the waistline WL to the groin (cross-leg line CRL), and in the lateral hind thigh region R3, which is located wider than the posterior center line CL2. On the front, sweating was highest in the anterior central region R4, along the anterior center line CL1, from the hip line HL to the knee line KL, and in the above-knee region R5. On the other hand, sweating was low in the anterior inner thigh region R6 and the posterior inner thigh region R7. From the experimental results, it was found that the sweating points were the axillary region R1, gluteal region R2, lateral hind thigh region R3, anterior central region R4, and above-knee region R5.

[0023] Next, we will describe an experiment to investigate thermoreceptor points. This experiment involves measuring the temperature perception of subjects and presenting the results of the investigation into thermoreceptor points. More specifically, the sensitivity of temperature perception in each part of the lower body was measured.

[0024] The temperature sensation threshold of the lower body was measured using a general-purpose temperature sensation threshold measuring device. The environmental conditions were 28°C and 50% RH (artificial climate chamber). Ten male subjects participated, and temperature sensation was measured at 34 locations on the right side of the lower body.

[0025] The above experiment revealed that different parts of the lower body have different sensitivity to temperature. In particular, on the front, sensitivity to temperature was high in the anterior inner thigh region R6, which is located medially to the anterior midline CL1 shown in Figure 4 and extends from the groin to above the knee. On the other hand, sensitivity to temperature was low lateral to the anterior midline CL1 and below the knee line KL. On the back, sensitivity to temperature was high in the gluteal region R2, which extends from the waistline WL to the groin (cross-leg line CRL), and in the posterior inner thigh region R7, which is located laterally to the right posterior midline CL2. On the other hand, sensitivity to temperature was low in the flank region R1, which is lateral to the posterior midline CL2. Therefore, the key points for temperature sensation were found to be the anterior inner thigh region R6, the gluteal region R2, and the posterior inner thigh region R7.

[0026] Based on the above results, it is preferable that in this embodiment, the lower garment 1 does not have the heat-retaining packs 4 and 5 placed at the aforementioned sweating points where sweating is high and stuffiness is likely to occur, while the heat-retaining packs 4 and 5 are placed at the aforementioned warming points where the sensitivity to temperature is high.

[0027] The arrangement of the heat-retaining packs 4 and 5 in this embodiment will be described with reference to Figures 1 to 3, 5 and 6. Figure 5 is an unfolded view of the left front panel 21 as seen from the front of the wearer. Figure 6 is an unfolded view of the left back panel 31 as seen from the back of the wearer. Since the left front panel 21 and the right front panel 22, and the left back panel 31 and the right back panel 32 are symmetrical with respect to the center line CL, only the left front panel 21 and the left back panel 31 are shown in Figures 5 and 6, and the explanation of the right front panel 22 and the right back panel 32 is omitted.

[0028] As shown in Figures 1 and 5, the front insulation packs 41 and 42 are positioned on the front of the garment 2 so as to face the wearer. Since the front insulation packs 41 and 42 are constructed by enclosing the filling material in woven or knitted fabric, the front insulation packs 41 and 42 expand toward the wearer, increasing the degree of contact with the wearer.

[0029] The front insulation packs 41 and 42 are a pair of first insulation packs 41 and 42, one on each side of the center line CL. The pair of first insulation packs 41 and 42 are roughly rectangular in shape. The pair of first insulation packs 41 and 42 consists of a left first insulation pack 41 located at a position corresponding to the inner thigh portion (front inner thigh region R6) on the left front panel 21, and a right first insulation pack 42 located at a position corresponding to the inner thigh portion (front inner thigh region R6) on the right front panel 22.

[0030] The first thermal packs 41 and 42 are positioned vertically between the crossover line CRL and the knee line KL, and horizontally inward from the anterior center line CL1. The first thermal packs 41 and 42 are positioned adjacent to the lower part of the crossover line CRL. In other words, the pair of left and right first thermal packs 41 and 42 are positioned to avoid the portion corresponding to the side seam region R1 and the anterior center region R4.

[0031] More specifically, as shown in Figure 5, each first insulation pack 41, 42 has an upper edge 41a, 42a that slopes downward toward the inside in the width direction, an inner edge 41b, 42b that extends downward toward the outside in the width direction from the lower end of the upper edge 41a, 42a along the inner leg line IL, a lower edge 41c, 42c that slopes upward toward the outside in the width direction from the lower end of the inner edge 41b, 42b, and an outer edge 41d, 42d that extends upward along the front center line CL1 from the outer end of the lower edge 41c, 42c.

[0032] The separation distance D1 between the left and right pair of front insulation packs 41, 42 and the inner leg line IL is preferably 30 mm or more and 50 mm or less, and in this embodiment it is set to 33 mm. In this embodiment, the separation distance D1 is the distance between the inner edges 41b, 42b of the left and right pair of front insulation packs 41, 42 and the inner leg line IL, and refers to the shortest distance between them. Because the left and right pair of front insulation packs 41, 42 and the inner leg line IL are separated, front inner leg passages 21a, 22a are formed around the inner leg line IL region, extending in the vertical direction and not having insulation packs placed therein. If the separation distance D1 is less than 30 mm, it tends to be difficult to sew, and from the viewpoint of sewability, it is preferable to set a predetermined separation distance D1 between the inner edges 41b, 42b of the front insulation packs 41, 42 and the inner leg line IL. Furthermore, by setting a predetermined separation distance D1, it is possible to prevent the heat-retaining packs from concentrating on the inner thigh area when worn, thereby reducing chafing, stuffiness, and discomfort caused by the concentration of heat-retaining packs. On the other hand, if the separation distance D1 exceeds 50 mm, the width of the heat-retaining pad becomes smaller, which tends to reduce the heat-retaining effect.

[0033] The distance D2 between the pair of front insulation packs 41 and 42 and the front center line CL1 is preferably 15 mm or more and 35 mm or less, and in this embodiment it is set to 15 mm. In this embodiment, the distance D2 is the distance between the outer edges 41d and 42d of the pair of front insulation packs 41 and 42 and the front center line CL1, and refers to the shortest distance between them. By separating the pair of front insulation packs 41 and 42 and the front center line CL1, the insulation packs can be placed while avoiding the front center region R4, which is one of the sweating points. Also, if the insulation packs are placed on the front center line CL1, the aesthetic appeal of the silhouette may be impaired when worn. For example, the part where the insulation packs are placed will spread out to the sides, making it look wider when viewed from the front. In addition, if the insulation packs are placed on the front center line CL1, it may be difficult to fold the garment along the front center line CL1. On the other hand, if the spacing D2 exceeds 35 mm, the width of the heat-retaining pad becomes smaller, which tends to reduce the heat-retaining effect.

[0034] The distance D3 between the pair of front thermal packs 41 and 42 and the knee line KL is preferably 70 mm to 120 mm, and in this embodiment, it is set to 94 mm. In this embodiment, the distance D3 is the distance between the lower edges 41c and 42c of the pair of front thermal packs 41 and 42 and the knee line KL, and refers to the shortest distance between them. By separating the pair of front thermal packs 41 and 42 and the knee line KL, the thermal packs can be positioned while avoiding sweat points that spread continuously from the side seam area R1 to the upper knee area R5. If the thermal packs are positioned on the knee line KL, bending and straightening of the knee may be hindered, or the knee area may spread laterally when worn, impairing the aesthetic appearance. On the other hand, if the distance D3 exceeds 120 mm, the length of the thermal pad becomes shorter, which tends to reduce the thermal insulation effect.

[0035] As shown in Figure 5, the left and right front panels 21 and 22 are each provided with front pockets 25 that are offset outward in the width direction relative to the front center line CL1. The front pockets 25 overlap the upper part of the first insulation packs 41 and 42 and are provided spanning from the waistline WL to the hip line HP and the thigh line CRL. The front pockets 25 have a bag-like portion made of mesh fabric or the like that is connected to the side seam SL of the front panel 21 and the back panel 31, and have a pocket opening 25a that opens at the side seam SL. The internal space and external space of the lower garment 1 are in communication via the front pockets 25 and the pocket openings 25a. This allows for ventilation of the warm air that may be generated in the internal space of the lower garment 1 in the area corresponding to the side seam region R1 and the front center region R4, via the front pockets 25 and the pocket openings 25a.

[0036] As shown in Figures 3 and 6, the rear insulation pack 5 has a pair of left and right second insulation packs 51, 52, a pair of left and right third insulation packs 53, 54, and a pair of left and right fourth insulation packs 55, 56, which are positioned on both sides of the center line CL in the width direction of the rear body 3.

[0037] Each of the rear insulation packs 51, 52, 53, 54, 55, and 56 is positioned on the back of the garment 3 so as to face the wearer 9. Each of the rear insulation packs 51, 52, 53, 54, 55, and 56 is constructed by enclosing the filling material in a woven or knitted fabric, so that each of the rear insulation packs 51, 52, 53, and 54 expands toward the wearer 9, increasing the degree of contact with the wearer 9.

[0038] The pair of left and right second insulation packs 51 and 52 are polygonal in shape. The pair of left and right second insulation packs 51 and 52 include a left second insulation pack 51 located at a position corresponding to the inner thigh portion (rear inner thigh region R7) on the left back panel 31, and a right second insulation pack 52 located at a position corresponding to the inner thigh portion (rear inner thigh region R7) on the right back panel 32.

[0039] The pair of left and right second posterior insulation packs 51 and 52 are positioned vertically between the cross-leg line CRL and the knee line KL, and horizontally biased medially relative to the posterior center line CL2. In other words, the pair of left and right second insulation packs 51 and 52 are positioned to avoid the portion corresponding to the posterior lateral region R3 of the thigh.

[0040] More specifically, as shown in Figure 6, the left and right pair of second insulation packs 51, 52 have upper edges 51a, 52a extending horizontally in the width direction along the crossover line CRL, upper inner edges 51b, 52b extending downward from the inner ends of the upper edges 51a, 52a, lower inner edges 51c, 52c sloping downward in the width direction outward from the lower ends of the upper inner edges 51b, 52b along the inner leg line IL, lower edges 51d, 52d sloping upward in the width direction outward from the lower ends of the lower inner edges 51c, 52c, and outer edges 51e, 52e sloping upward in the width direction outward from the upper ends of the lower edges 51d, 52d.

[0041] The separation distance D4 between the second insulation packs 51, 52 and the inner leg line IL is preferably 30 mm or more and 60 mm or less, and in this embodiment it is set to 40 mm. In this embodiment, the separation distance D4 is the distance between the lower inner edges 51c, 52c of the second insulation packs 51, 52 and the inner leg line IL, and refers to the shortest distance between them. By arranging the second insulation pack 51 and the inner leg line IL at a distance from each other, rear inner leg air passages 31a, 32a that extend in the vertical direction and do not have insulation packs are formed around the inner leg line IL region. If the separation distance D4 is less than 30 mm, it tends to become difficult to sew, and from the viewpoint of sewability, it is preferable to set a predetermined separation distance D4 between the lower inner edges 51c, 52c of the second insulation packs 51, 52 and the inner leg line IL. Furthermore, by setting a predetermined separation distance D4, the concentration of the heat-retaining packs on the inner thigh area during wear can be suppressed, thereby reducing chafing, stuffiness, and discomfort caused by the concentration of heat-retaining packs. On the other hand, if the separation distance D4 exceeds 60 mm, the width of the heat-retaining pad becomes smaller, which tends to reduce the heat-retaining effect.

[0042] The distance D5 between the second heat-retaining packs 51 and 52 and the knee line KL is approximately half the distance D6 between the crossover line CRL and the knee line KL. The distance D5 is preferably 150 mm or more and 220 mm or less, and in this embodiment it is set to 170 mm. In this embodiment, the distance D5 is the distance between the lower edges 51d and 52d of the second heat-retaining packs 51 and 52 and the knee line KL, and refers to the shortest distance between them. By positioning the second heat-retaining packs 51 and 52 and the knee line KL at a distance, the heat-retaining packs can be positioned while avoiding the sweating points in the knee area, which are generally sweating points. If the heat-retaining packs are positioned near the knee line KL, they may overlap with the back of the knee when the knee is bent, which may cause difficulty in bending the knee and discomfort. On the other hand, if the distance D6 exceeds 220 mm, the length of the heat-retaining pad becomes shorter, which tends to reduce the heat-retaining effect.

[0043] As shown in Figures 3 and 6, the pair of left and right third insulation packs 53 and 54 are generally rectangular in shape. The pair of left and right third insulation packs 53 and 54 include a third left rear insulation pack 53 located in a position corresponding to the inner width direction of the buttock area R2 on the left rear panel 31, and a third right rear insulation pack 54 located in a position corresponding to the inner width direction of the buttock area R2 on the right rear panel 32.

[0044] The third left rear insulation pack 53 and the third right rear insulation pack 54 are located above the pair of left and right second insulation packs 51 and 52, respectively. In this embodiment, the third insulation packs 53 and 54 are provided integrally with the second insulation packs 51 and 52. The third insulation packs 53 and 54 and the second insulation packs 51 and 52 are integrally formed by a single insulation pack.

[0045] The pair of left and right third insulation packs 53, 54 are positioned vertically between the crossover line CRL and the waistline WL, and horizontally biased inward relative to the posterior center line CL2. In other words, the pair of left and right third insulation packs 53, 54 are positioned to avoid the portion corresponding to the side seam region R1, and to cover the horizontally inward side of the buttock region R2.

[0046] More specifically, as shown in Figure 6, the left and right pair of third insulation packs 53, 54 have upper edges 53a, 54a that incline upward toward the inside in the width direction, inner edges 53b, 54b that incline downward toward the inside in the width direction from the upper ends of the upper edges 53a, 54a, lower edges 53c, 54c that extend horizontally toward the inside in the width direction along the connecting line from the lower ends of the inner edges 53b, 54b, and outer edges 53d, 54d that incline upward toward the outside in the width direction from the outer ends of the lower edges 53c, 54c.

[0047] There is no gap between the third insulation packs 53, 54 and the second insulation packs 51, 52. The separation distance D7 between the third insulation packs 53, 54 and the center line CL is preferably 30 mm or more and 50 mm or less, and in this embodiment it is set to 33 mm. In this embodiment, the separation distance D7 is the distance between the inner edges 53b, 54b of the third left rear insulation pack 53 and the second right rear insulation pack 54 and the center line CL, and refers to the shortest distance between them. By arranging the third insulation packs 53, 54 and the center line CL at a distance from each other, as shown in Figure 3, center line air passages 31b, 32b extending vertically are formed in the peripheral area of ​​the body center line CL corresponding to the center line of the wearer 9. If the separation distance D7 is less than 30 mm, it tends to be difficult to sew, and if the separation distance D7 exceeds 50 mm, the width of the insulation pad becomes smaller, so the insulation effect tends to decrease.

[0048] The pair of left and right fourth insulation packs 55 and 56 are generally rectangular in shape. The pair of left and right fourth insulation packs 55 and 56 include a fourth left rear insulation pack 55 located at a position corresponding to the outer width direction of the buttock area R2 on the left rear panel 31, and a fourth right rear insulation pack 56 located at a position corresponding to the outer width direction of the buttock area R2 on the right rear panel 32.

[0049] The fourth left rear insulation pack 55 and the fourth right rear insulation pack 56 are located on the widthwise outer side of the pair of third insulation packs 53 and 54, respectively. The fourth insulation packs 55 and 56 are spaced apart from the third insulation packs 53 and 54, respectively.

[0050] The pair of left and right fourth insulation packs 55, 56 are positioned vertically between the waistline WL and the kneeline KL, and horizontally beyond the posterior centerline CL2 and horizontally inward from the side seam SL. In other words, the pair of left and right third insulation packs 53, 54 are positioned to avoid the portion corresponding to the side seam region R1, and to cover the horizontal outer side of the buttock region R2.

[0051] More specifically, the pair of left and right fourth insulation packs 55, 56 have upper edges 55a, 56a that slope upward toward the inside in the width direction, inner edges 55b, 56b that slope downward toward the inside in the width direction from the upper ends of the upper edges 55a, 56a, lower edges 55c, 56c that slope downward toward the outside in the width direction from the lower ends of the inner edges 55b, 56b, and outer edges 55d, 56d that extend upward from the outer ends of the lower edges 55c, 56c generally along the side lines.

[0052] The separation distance D8 between the pair of left and right fourth insulation packs 55, 56 and the side seam SL is preferably 30 mm or more and 50 mm or less, and in this embodiment it is set to 38 mm. In this embodiment, the separation distance D8 is the distance between the outer edges 55d, 56d of the pair of left and right fourth insulation packs 55, 56 and the side seam SL, and refers to the shortest distance between them. Because the pair of left and right fourth insulation packs 55, 56 and the side seam SL are separated, as shown in Figure 2, side passages 31c, 32c are formed around the side seam region R1 that extend in the vertical direction and do not have insulation packs. Furthermore, if the separation distance D8 is less than 30 mm, sewing tends to become difficult, and if the separation distance D8 exceeds 50 mm, the width of the insulation pad becomes smaller, which tends to reduce the insulation effect.

[0053] The lower ends of the fourth insulation packs 55 and 56 are located above the knee line KL, and in this embodiment, the distance D10 between the fourth insulation packs 55 and 56 and the knee line KL is located above approximately half the distance D6 between the crossover line CRL and the knee line KL.

[0054] A gap is provided between the fourth insulation packs 55, 56 and the second insulation packs 51, 52 and the third insulation packs 53, 54. The separation distance D9 between the fourth insulation packs 55, 56 and the second insulation packs 51, 52 and the third insulation packs 53, 54 is preferably 25 mm or more and 60 mm or less, and in this embodiment it is set to 30 mm. In this embodiment, the separation distance D9 is the distance between the inner edges 55b, 56b of the fourth insulation packs 55, 56 and the outer edges 53d, 54d of the third insulation packs 53, 54, and refers to the shortest distance between them. By arranging the third insulation packs 53, 54 and the fourth insulation packs 55, 56 at a distance from each other, buttock air passages 31d, 32d extending vertically are formed in the intermediate region in the width direction of the buttock region R2.

[0055] As shown in Figure 3, the buttock air passages 31d and 32d extend generally in the vertical direction when worn, and are positioned in the center of the width direction of each of the left and right buttock regions R2. The lower edges 51d, 52d of the second insulation packs 51, 52 and the lower edges 55c, 56c of the fourth insulation packs 55, 56 are inclined upward toward the buttock air passages 31d, 32d.

[0056] The left and right back panels 31 and 32 are each provided with ventilation openings 31e and 32e between the third insulation packs 53 and 54 and the fourth insulation packs 55 and 56, and at least between the waistline WL and the hipline HL. The ventilation openings 31e and 32e only need to have a configuration that connects the internal space and the external space of the lower garment 1, and may be, for example, the opening of a pocket made of mesh fabric or the like. The ventilation openings 31e and 32e are formed to communicate with the buttock air passages 31d and 32d.

[0057] In this embodiment, each insulation pack is provided with stitching to suppress the shifting of the filling material. As shown in Figure 5, the stitching S1 of the first insulation packs 41 and 42 is provided so as to be inclined upward from the inside to the outside in the width direction. As shown in Figure 6, the stitching S2 of the second and third insulation packs 51, 52, 53, and 54 is provided so as to be inclined upward from the inside to the outside in the width direction. The stitching S3 of the fourth insulation packs 55 and 56 is provided so as to be inclined upward from the outside to the inside in the width direction. The stitching S2 and stitching S3 are inclined upward toward the buttock air passages 31d and 32d, respectively.

[0058] The lower garment 1 according to this embodiment provides the following effects.

[0059] The lower garment 1 has a front panel 2 and a back panel 3, the front panel 2 has a left front panel 21 that covers the front of the left leg and a right front panel 22 that covers the front of the right leg, and has a pair of left and right first thermal packs 51, 52 provided at positions corresponding to the inner thigh area on the left front panel 21 and the right front panel 22, respectively, and the pair of left and right first thermal packs 51, 52 are positioned inward in the width direction from the front center lines CL1, CL2 of the left front panel 21 and the right front panel 22, respectively.

[0060] With this configuration, the first heat-retaining packs 41 and 42 are placed in the anterior inner thigh area (anterior inner thigh region R6), which is a point of warmth, while no heat-retaining packs are placed in the side-lying area R1, which is a sweating point from the outer side of the thigh to the knee. This ensures warmth at the points of warmth while suppressing stuffiness at the sweating points.

[0061] The back panel 3 has a left back panel 31 that covers the back of the left leg and a right back panel 32 that covers the back of the right leg, and has a pair of left and right second thermal insulation packs 51, 52 provided at positions corresponding to the inner thigh area (rear inner thigh region R7) on the left back panel 31 and the right back panel 32, respectively, and the pair of left and right second thermal insulation packs 51, 52 are offset inward in the width direction with respect to the rear center line CL2 of the left back panel 31 and the right back panel 32, respectively.

[0062] This configuration places the second heat-retaining packs 51 and 52 in the posterior inner thigh region R7, which is a heat-sensing point, while leaving no heat-retaining pack in the posterior outer thigh region R3. This further improves heat retention while suppressing stuffiness at sweating points.

[0063] The garment further includes a pair of left and right third insulation packs 53 and 54, positioned on the left back panel 31 and the right back panel 32, respectively, corresponding to the buttocks, with the pair of left and right third insulation packs 53 and 54 being biased inward in the width direction relative to the back center line CL2.

[0064] This configuration allows the buttocks to be kept warm by positioning the third heat-retaining packs 53 and 54 inside the buttock region R2, which is another point of heat sensation. On the other hand, since the buttock region R2 is also a point of sweating, by unevenly distributing the third heat-retaining packs 53 and 54 relative to the posterior center line CL2, stuffiness in the buttocks can be suppressed compared to when the entire buttock region R2 is covered by the third heat-retaining packs 53 and 54.

[0065] It further comprises a pair of left and right third insulation packs 53, 54, which are located on the widthwise outer side and spaced apart from the left and right third insulation packs 53, 54, and a pair of left and right fourth insulation packs 55, 56.

[0066] This configuration allows for further warming of the buttocks by positioning the fourth insulation packs 55 and 56 outside the buttock region R2, which is another area of ​​increased body temperature. On the other hand, since the buttock region R2 is also a sweating point, separating the third insulation packs 53 and 54 from the fourth insulation packs 55 and 56 helps to reduce stuffiness in the buttocks compared to when the entire buttock region R2 is covered by the third insulation packs 53 and 54 and the fourth insulation packs 55 and 56.

[0067] Between the third insulation packs 53 and 54 and the fourth insulation packs 55 and 56, there are vertically extending buttock air passages 31d and 32d.

[0068] This configuration allows for better suppression of dampness in the buttocks area, which is also a sweating point, through the buttock air passages 31d and 32d.

[0069] The lower edges 51d and 52d of the second insulation packs 51 and 52 are inclined upward toward the buttock air passages 31d and 32d.

[0070] This configuration makes it easier for air from the sweating points around the lower edges 51d, 52d of the second insulation packs 51, 52 to flow towards the buttock air passages 31d, 32d.

[0071] The lower edges 55c and 56c of the fourth insulation packs 55 and 56 are inclined upward toward the buttock air passages 31d and 32d.

[0072] This configuration makes it easier to direct air from the sweating points around the lower edges 55c and 56c of the fourth insulation pack 55 and 56 upward toward the buttock air passages 31d and 32d.

[0073] Above the buttock air passages 31d and 32d, vents 31e and 32e are provided that communicate with the buttock air passages 31d and 32d.

[0074] This configuration makes it easier to sweep the air that flows into the buttock air passages 31d and 32d through the vents 31e and 32e.

[0075] The second insulation packs 51 and 52 and the third insulation packs 53 and 54 are formed integrally.

[0076] This configuration allows for continuous heat retention between the adjacent thermal sensation points, the posterior inner thigh region R7 and the buttock region R2. Compared to the case where the second heat retention packs 51, 52 and the third heat retention packs 53, 54 are separated, this configuration makes it easier to achieve heat retention at the base of the leg (crown line CRL), which is one of the thermal sensation points between the inner thigh and the buttocks.

[0077] In this embodiment, a configuration in which the left and right pairs of 1st to 4th insulation packs 41, 42, 51, 52, 53, 54, 55, and 56 are polygonal or rectangular has been described, but the embodiment is not limited to this, and each insulation pack may be elliptical or semicircular.

[0078] In this embodiment, the insulation pack has been described as comprising a pair of left and right first to fourth insulation packs 41, 42, 51, 52, 53, 54, 55, and 56. However, it is not limited to this configuration, and only one of the left and right pairs of first to fourth insulation packs 41, 42, 51, 52, 53, 54, 55, and 56 may be provided, or several may be combined.

[0079] In this embodiment, a configuration has been described in which the thermal insulation packs 4 and 5 are placed on the inside (wearer side) of the front body 2 and / or back body 3, but the invention is not limited to this configuration. The thermal insulation packs 4 and 5 may be sewn to the front body 2 and / or back body 3 in a thermal insulation pack placement area formed by cutting out a part of the front body 2 and / or back body 3 to the shape of the corresponding thermal insulation pack 4 and 5.
