Cocoon Mummy Liner

The CoolMax fabric provides a temperature boost of approximately +8.4°F. While it adds a noticeable layer of comfort, it is designed primarily for moisture management and hygiene rather than extreme cold insulation.

Yes, the tapered mummy shape is designed to be compatible with almost all standard mummy sleeping bags. The drawstring hood and boxed foot end help ensure it stays in place without bunching up while you sleep.

Yes, CoolMax is specifically engineered to be soft and breathable. It wicks moisture away from your body, which helps you stay dry and comfortable even if you tend to run warm at night.

It is quite compact. When packed into its included nylon stuff sack, it measures just 3 inches by 6 inches and weighs only 10.8 ounces, making it easy to tuck into a corner of your backpack.
