Common sleeping bags come in 3 shapes, Mami style, envelope style and beer barrel style. Mummy style is also called mummy style or mummy style. This kind of sleeping bag has shoulder width and narrow feet. The shoulder width is generally 75 to 85 cm, and the footstep width is 35 to 45 cm. The Mami-style sleeping bag is a sleeping bag shape that can achieve good warmth under the same weight. It is suitable for use in cold seasons. As the name suggests, the envelope-style sleeping bag has the same width as the feet and is like an envelope. This sleeping bag is looser and suitable for summer and warm seasons. People with large bodies; the combination of the first two of the hybrid sleeping bag, mostly envelope sleeping bag plus a Mami-style hat.
The internationally popular sleeping bag is a small square cap with a streamlined human body (the wide part is not on the neckline, but on the shoulders and elbows). The previous big round hat not only increases the weight, but also is not conducive to keeping warm. Some people call this new type of sleeping bag a “beer keg”, while others call it a “cocoon style”. In fact, it is just an alienation of the first two sleeping bags. Its design has absorbed the advantages of the first two sleeping bags and abandoned them. The shortcomings of the first two have greatly improved the comfort of carrying and use.
