COCOON Premium Cotton MummyLiner Natural | Warmth, Comfort & Easy Entry

Elevate Your Sleep Anywhere

The COCOON Premium Cotton MummyLiner in Natural is a soft, breathable layer you can slip between you and your sleeping bag. Its cotton fibers feel gentle against skin, delivering a calming, natural touch that enhances comfort on cool nights around the campfire or in shared sleeping spaces.

One standout benefit is enhanced warmth—the liner can add up to 5.3°F of extra coziness to your sleeping setup. This extra layer helps you stay comfortable when temperatures dip, without relying on heavier bags. The result is a calmer, more settled night that supports a restful morning.
