One is to ensure waterproofness, and the other is to improve heat retention. The down or synthetic insulation used in sleeping bags not only becomes uncomfortable when wet due to rain or bad weather but also reduces its heat retention. In snow-free seasons, especially in rainy weather, it is necessary to protect the sleeping bag from getting wet. Many people prepare sleeping bag covers to ensure waterproofness when bad weather is expected during spring, summer, and autumn hikes. In cold environments such as snowy or winter conditions, it is necessary to cope with cold in addition to wetness. During this period, a sleeping bag cover is essential for improving the sleeping bag's heat retention, and GORE-TEX material with excellent waterproofness and breathability is recommended.
