About the Cocoon MummyLiner Silk

Cocoon are dedicated to crafting extremely lightweight, high quality sleeping bag liners with a compact travel design. The Silk MummyLiner gives you a tapered sleep sack with a silky smooth finish for next-to-skin softness. A breathable construction responds to changing temperatures making it ideal for tropical and alpine adventures.

The MummyLiner can be used on its own in warmer climes, or as a sleeping bag liner to boost insulation in cooler weather. They also help in keeping your sleeping bag cleaner and fresher for longer by reducing the build up of dirt and oils. Great for backpackers staying in hotels and youth hostels or for outdoors adventures; from camping trips to trekking between alpine huts and anywhere else you choose to hang your hat for the night.

The minimalist design takes up little pack space and offers peace of mind. Should the nights turn cool or the accommodation fall short of expectations you can curl up in the comfort and warmth of the MummyLiner for a good night's sleep. At a micro 135g it's small enough to fit in a pocket!

The Silk MummyLiner from Cocoon gives you a travel essential with assured quality and comfort.
