Cocoon CoolMax MummyLiner by COCOON – Fast-Drying, Moisture-Wicking Travel Liner

Overview

The Cocoon CoolMax MummyLiner from COCOON is crafted for hikers, travelers, and campers who value dry, comfortable rest. It uses 100% Polyester CoolMax, a fabric celebrated for fast drying and moisture management. The four-channel fibers help move sweat away from your body, promoting a cooler, drier feel as you sleep or take a quiet break in the tent or hostel lounge.

Why CoolMax matters

In real-world settings, staying dry translates to improved comfort between campsite breaks or overnight stays, especially in humid climates. The CoolMax fabric is highly breathable, allowing air to circulate and moisture to evaporate efficiently. Best of all, this liner is easy to care for, so you can refresh it quickly between outings.
