Sea to Summit Thermolite Sleeping Bag Liner

The newest innovation in sleeping bag liners, this compact Sea to Summit thermolite liner adds up to 8°C to the comfort rating of your sleeping bag (1-2 seasons) and does this while only weighing 248 grams and packing down to the size of 13 x 9cm! Perfect for travellers who will be travelling through a variety of climates, the Thermolite reactor liner can be used in conjunction with a lightweight 1-2 season sleeping bag. It can also be used alone in warmer climates.

It's also odour resistant, machine washable and will help to keep your sleeping bag clean. Thermolite® is a hollow core fibre that provides extraordinary warmth for its weight and remains extremely breathable. With the stretchy knit fabric that moves with you and a drawcord hood, this liner is perfect for people who like to move when sleeping!
