What is a Mummy Bag?
A mummy bag is a type of sleeping bag which narrows at either end to conserve heat, causing it to look slightly like an Egyptian mummy case. Many manufacturers of sleeping bags make mummy bags, which are usually rated for extremely cold weather. A variety of materials are used to make mummy bags and liners, to meet varying consumer needs. Consumers can order mummy bags directly from the manufacturer, or visit an outdoor supply store to acquire one.
