Cocoon MummyLiner Thermolite

The Thermolite Silkweight liner is rated to add 11.3 degrees Fahrenheit of warmth to your existing sleep system. It is designed to bridge the gap between seasons rather than serve as a standalone sleeping bag.

Not at all. It packs down to a very compact 6 inches by 3 inches and weighs only 5.6 ounces, making it an excellent choice for ultralight backpacking where every ounce counts.

It has a unique feel because it is a hybrid blend of ripstop silk and recycled hollow-core fibers. While it retains the smooth, premium feel of silk, the synthetic fibers add durability and moisture-wicking capabilities that pure silk lacks.

Yes, it is machine washable. Because of the synthetic fiber blend, it also dries about 20% faster than many other insulating liners, which is helpful when you are on the move.

Yes, the drawstring hood allows you to cinch the opening around your face, which significantly reduces heat loss. Combined with the contoured foot box, it creates a more efficient thermal seal than a standard rectangular liner.

Yes, the dimensions are 95 inches by 36 inches at the shoulders, tapering to 22 inches at the feet. This profile is specifically engineered to match the shape of most mummy bags without bunching up inside.
