Sleeping bag

In camping and other outdoor activities, a sleeping bag is a protective "bag" for sleeping, analogous to a bed and blanket. Its primary purpose is to provide warmth and insulation. It also protects, to some extent, against wind, precipitation, and exposure to view, but a tent performs those functions better. The bottom surface also provides some cushioning, but a sleeping pad is usually used for that purpose. A bivouac sack (bivy) is a waterproof cover for a sleeping bag that may be used in place of a tent, if rain or very cold temperatures are not expected.
