Exped Sleepwell Thermolite Liner

Available in mummy form, the Thermolite EcoMade® liner is cozy and warm, pushing the comfort limit of the sleeping bag down a whole 8 degrees Celsius (or about 14 degrees Fahrenheit). It’s made from recycled polyester, and is aimed at anyone who wants to significantly expand the use and temperature range of their sleeping bag.

It can be packed smaller than a cotton liner, absorbs moisture quickly and transports it just as quickly to the outside. A further highlight, the Sleepwell Thermolite EcoMade® liner dries about 50 percent faster than conventional cotton. It is equipped with cord adjustable hood and a 3D foot box.
