Based on fillers.</p><p style="user-select: auto;"><br></p><p style="user-select: auto;">1. The filler is generally divided into two types, one is fiber, which is what we call cotton sleeping bag. The other is down.</p><p style="user-select: auto;"><br></p><p style="user-select: auto;">2. Fiber: There are many types of fiber cotton, from stretch cotton to 3-hole, 4-hole or even 7-hole cotton, as well as 3D cotton (Polarguard 3D produced by INVISTA) and imitation silk cotton (Primaloft One). In terms of insulation performance, 7 holes are better than 4 holes, and 4 holes are better than 3 holes. The principle is very simple, that is, the more isolated air that can be enclosed, the less heat is exchanged, and the better the insulation performance.</p><p style="user-select: auto;"><br></p><p style="user-select: auto;">3. Down: There are many varieties of down, and the weight difference is also very large. As long as you do n’t take the duck feathers, you can still guarantee the thermal insulation performance. There are two main standards that determine the thermal insulation performance of down. One is the velvet content, which is 80% or 85% on the label of the sleeping bag, which means that the velvet content in the down is 80% or 85%. Another is the bulkiness, which refers to the volume occupied by a certain amount of down on a constant weight of pressure. It is the main factor that determines the thermal performance. Therefore, it is an important indicator of down quality.</p>
