[0012] Furthermore, the first windproof layer is made of GORE-TEX fabric, and the second windproof layer is made of GORE-TEX fabric.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention significantly improves the windproof performance of the backpack by setting up a first windproof layer and a second windproof layer, effectively blocking the intrusion of cold wind. By setting up a first insulation layer and a second insulation layer, it significantly improves the insulation performance of the backpack, thereby greatly enhancing its practicality.

[0022] Please see Figure 1-3 A windproof and warm backpack includes a backpack body 1, with two shoulder straps 2 installed on the backpack body 1. The backpack body 1 includes a base layer 101, a first insulation layer 102, a second insulation layer 103, a first windproof layer 104, and a second windproof layer 105. The first insulation layer 102 is fixedly connected to the top of the base layer 101.

[0023] Specifically, the bottom of the base layer 101 is fixedly connected to the second insulation layer 103, and the top of the first insulation layer 102 is fixedly connected to the first windproof layer 104.

[0024] In practice, the bottom of the second insulation layer 103 is fixedly connected to the second windproof layer 105, and the first windproof layer 104 and the second windproof layer 105 have the same thickness.

[0025] Specifically, the first insulation layer 102 includes a milk protein fiber woven layer 1021, a hollow three-dimensional fiber woven layer 1022, and a cashmere fiber woven layer 1023.

[0026] In specific implementation, a milk protein fiber woven layer 1021 is fixedly connected to the top of the base layer 101, a hollow three-dimensional fiber woven layer 1022 is fixedly connected to the top of the milk protein fiber woven layer 1021, and a cashmere fiber woven layer 1023 is fixedly connected to the top of the hollow three-dimensional fiber woven layer 1022.

[0027] Specifically, the second insulation layer 103 and the first insulation layer 102 are made of the same material, and the thickness of the second insulation layer 103 is the same as the thickness of the first insulation layer 102.

[0028] In practice, the first windproof layer 104 and the second windproof layer 105 are both made of GORE-TEX fabric. The GORE-TEX membrane is the core of this fabric, with 9 billion extremely small pores per square inch. The size of these pores is significant; they are smaller than water molecules but larger than gas molecules. This is the key to GORE-TEX fabric's waterproof and breathable properties. Water molecules cannot pass through these tiny pores, thus achieving waterproofing. Since the sweat molecules exhaled by the human body are smaller than these pores, sweat can easily pass through the fabric, achieving breathability. Furthermore, the irregular arrangement of the 9 billion micropores per square inch allows GORE-TEX to block the intrusion of cold wind, thus providing wind protection.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
