Mummy Liner Thermolight Radiator Cocoon
The extra warm COCOON Thermolite MummyLiners add 9°C to the temperature rating of your sleeping bag! Thermolite provides warmth and comfort at the lightest weight, even when wet. Its hollow-core fibers trap air for better insulation. Thermolite dries 20% faster than other insulating fabrics and 50% faster than cotton. It wicks moisture away from the skin to the surface of the fabric where it can evaporate more quickly.
