Description

Technical Field

[0002] Down jackets are warm outerwear filled with feathers or goose down, usually used to keep the body warm in cold winter. The filling of down jackets has excellent thermal insulation properties, which can effectively block cold air and make the wearer feel warm and comfortable;

[0003] Down jackets are usually light, soft, and breathable. They also have good warmth retention and durability, making them one of the must-have fashionable and warm items in winter.

[0004] In the utility model patent with patent authorization announcement number CN216533907U, an ultra-thin down jacket is disclosed, including a body, a hood is fixedly connected to the top of the body, sleeves are fixedly connected to the sides of the body, the front side of the body is a wear-resistant layer, a corrosion-resistant layer is fixedly connected to the surface of the wear-resistant layer, a pressure-relief layer is fixedly connected to the surface of the corrosion-resistant layer, the interior of the pressure-relief layer is a cavity, a down storage cover is placed inside the cavity, a thermal insulation layer is fixedly connected to the surface of the pressure-relief layer, and an elastic sealing ring is fixedly connected to the bottom of the body.

[0005] However, the existing thin-layer thermal insulation down jackets also have certain shortcomings. First, the existing thin-layer thermal insulation down jackets are mostly simply filled with feathers or goose down in the down jacket body to achieve the effect of keeping warm. Due to the limitation of the number of feathers or goose down filled in the down jacket body, the warmth retention effect of the down jacket is weak, and the tear resistance of the down jacket lining is poor.

[0006] Secondly, most of the existing thin-layer thermal insulation down jackets simply use the down jacket body to treat sweat and ventilation for the wearer in motion. Since the sweat glands under the armpits of the human body are relatively developed, the single down jacket body causes the problem of poor sweat and ventilation effects under the armpits.

[0007] Furthermore, the sleeves of the existing thin-layer thermal insulation down jackets are mostly open, which results in poor thermal insulation performance and wear resistance of the down jackets. Summary of the invention
