mummy sleeping bags
January 18th, 2010
This is the most common design for sleeping bags to be used outdoors. They are made close to the body and are called mummy sleeping bags because they resemble an Egyptian mummy case. They provide more warmth by hugging the body. When fully closed they leave only the nose and mouth exposed. This keeps air, which is a good insulator, trapped inside the bag.
Mummy bags may be one of your best bet for cold weather conditions but it has its limitations. Mummy bags force the user to sleep on their back, which some people may not like. They complain about feeling claustrophobic in this situation. They are also more expensive than regular rectangle sleeping bags. Considering these drawbacks, it is good to remember that there are other options.
