[Common textile manual] sleeping bag

The sleeping bag is a textile product used to keep the body warm during outdoor sleep. It was originally designed for people working in the field, but slowly its function has undergone great changes. Series products are ergonomically designed to meet the requirements of human sleep comfort. The fabric is made of high-grade waterproof material and the lining is made of pure cotton products or light and soft synthetic fiber products. Fillers use polyester, acrylic hollow fiber or down.

The difference in the grade and function of the sleeping bag is mainly due to the use of different fabrics and a warm layer.

Professional sleeping bags, especially high-quality adventure sleeping bags, are inseparable from down, and their down content should be above 80%.
