Why MummyLiners?
A MummyLiner is an extremely lightweight, tapered sleeping bag liner. It increases the temperature rating of your sleeping bag (up to 9° C) and protects your sleeping bag against dirt and sweat. It is always much easier to wash the liner – not the sleeping bag. In this way the liner extends the life span of your sleeping bag. Moreover, the high quality materials of COCOON MummyLiners are soft to your skin and guarantee a good night’s sleep!
