MummyLiners
Cocoons for the modern pioneer
A favorite of those looking for extra insulation, adventuring out on alpine backpacking trips, camping on porta ledges, or embarking into less-hospitable environments.
You put a load of trust into your mummy bag. Sometimes it’s the only thing that gets you through the night. But all the best gear and life-saving systems need a backup. That’s what COCOON® MummyLiners™ are for. When the wind is howling, the air is cold and the long day of adventure is catching up with you, unwind with peace of mind knowing that your MummyLiner can kick up the heat in your sleep system by up to an additional 16.2 degrees beyond your sleeping bags insulation rating.
Choose between COOOLMAX®, Flannel, Microfiber, or over 15 other options to customize the sleep system that fits your needs. There truly is no highly technical, high-performing sleeping bag liner out there that offers the versatility to compare.
