Thinking about getting a mummy winter sleeping bag? This article highlights the key points you should know. These sleeping bags weigh less than rectangular bags, providing excellent insulation per unit weight. Ideal for cold weather, they help trap body heat. However, they provide less space to move around, making them uncomfortable for sleepers who toss and turn. They feature tough insulation, so you won't be shivering and unable to sleep on cold nights. Winter sleeping bags are usually made with a waterproof breathable shell, so if you plan on sleeping out in snow, they will keep you warm and dry throughout the night. They are for serious cold and snow conditions, so you should only consider them if you'll only be sleeping outdoors in the coldest seasons.
