Adding additional warmth (8.4 degrees Fahrenheit) and increasing the longevity of your sleeping bag, the Cocoon MummyLiner CoolMax is a tapered bag liner. On balmy nights, the MummyLiner CoolMax may be all the coverage you need. Wicking, fast-drying CoolMax fabric makes this especially ideal for humid climates.
Each MummyLiner CoolMax includes its own integrated drawstring hood, a boxed foot-end and durable double-stitching. The MummyLiner CoolMax helps to keep your sleeping bag clean and, at the end of a trip, you can launder just the MummyLiner and extend the life of your sleeping bag by not subjecting it to frequent washings.
Measuring 86" x 33" (24" at the tapered foot), the Cocoon MummyLiner CoolMax weighs just 9.0 ounces and fits conveniently inside its own included stuff sack.
