When choosing a sleeping bag, we must pay attention to the temperature indicated on the sleeping bag. Usually sleeping bags will indicate two kinds of temperature: comfort temperature and extreme comfort temperature. The comfortable temperature indicates the temperature at which the user can fall asleep comfortably in a relaxed lying position. The sleeping bag is selected according to this standard. The limit temperature indicates the temperature that will not be frostbited.

However, down will lose its warmth retention ability when wet, and it is not easy to dry, but the synthetic fiber still has a good warmth retention ability when wet, and has a good quick-drying ability. In terms of price, down sleeping bags are more expensive. When choosing a sleeping bag, consider whether the environment is humid and whether there is a requirement for lightweight. Combine these two points to choose the right fabric. There is also a sleeping bag made of fleece, which is usually used in summer or in an environment above 25°C.

The envelope-style sleeping bag is as wide as an envelope. It is generally loose and has a large internal space. It has zippers on the sides and bottom. After opening, it can be used as a quilt, but it has a slightly lower warmth retention and is suitable for people who do not require high warmth retention. In addition, each sleeping bag will have a different size, so we can choose the corresponding size according to our height.
