The selection of sleeping bag material also marks the grade and price of the sleeping bag. The change of sleeping bag material also has a good and bad process. When people are not satisfied with a big, heavy sleeping bag, the lightweight, small sleeping bag becomes an inevitable substitute, so the compressibility is good, and the bag is inflated. High-quality sunny cotton replaces cheap, low-quality sunny cotton. In order to improve the performance of sleeping bags, some styles apply high-tech breathable fabrics to the outer fabrics of sleeping bags. The DRYLOFT fabrics of GORE, USA, are the most representative best materials. In order to pursue the use of perfection, down comfort sleeping bags are increasingly welcomed by campers. 80% of gray duck down, 90% of white goose down, and other excellent sleeping bags are on the market. Originally, only the sleeping bags used by mountaineers in extreme conditions entered the rucksack of ordinary campers.
At present, there are two main types of filling materials for sleeping bags in the market: First, down products can be divided into low-velvet sleeping bags and high-velvet sleeping bags. Generally containing more than 80% of the cashmere can be classified as high-grade sleeping bags, the following is a low-velvet sleeping bag. Down sleeping bag has the advantages of good compression, good warmth, light weight and small size. However, due to the fact that down is warm by expansion, the use of medium pressure in the lower part of the body is not very satisfactory, and the use of high-grade moisture-proof mats is required.
Because of the different cotton varieties, the clear cotton sleeping bags have great differences in warming indicators. At present, the clear cotton sleeping bag filling materials on the market include spray cotton, silicon-containing cotton, imitation silk cotton, Dupont cotton, Plaka 3D cotton and so on. Taking 300 g/m2 as an example, the thermal index of the sprayed cotton is about 5 degrees and the simulated silk is about -5 degrees, while the Plaka 3D cotton can reach the target temperature of -12 degrees. High-grade sleeping bags are generally marked with filling materials, and low-grade sleeping bags are less marked. The advantage of the clear cotton sleeping bag is that it is not easy to get wet, and the high quality sunny cotton also has good warmth, but it is generally less compressible.
