Amplify the cosiness and heat retention of your sleeping bag with the Sea to Summit Reactor Liner w/ Drawcord, which comes in two sizes. Designed with specialized Thermolite® Pro material, this liner is shaped in a mummy style and equipped with cutting-edge infrared technology and flexible stretch fabric to improve insulation. It offers a 12% thermal increase for 1-season sleeping bags and 6% for 3-season sleeping bags, making it ideal for moderately chilly camping and backpacking conditions.

The Thermolite Pro has been designed with specially engineered hollow fibres, similar to traditional Thermolite materials. However, this version also includes permanent ceramic pigments that effectively absorb infrared rays from the body and then reflect them back to the user. Tested in accordance with ASTM D1518-2014, This liner will add 12% thermal boost to a 1-season sleeping bag, and 6% to a 3-season sleeping bag.

Constructed with 100% textile waste, the Thermolite EcoMade fibres are both GRS-certified and provide comparable lightweight warmth and durability to traditional polymer materials, while also reducing carbon emissions.

The draw-cord footbox allows you to regulate your temperature more to your comfort. Keep it cinched up to keep in the warmth, if you get a little too hot, then open it up and let your feet breathe. You can also free your arms without taking the liner off, allowing you to carry out various tasks around camp whilst still keeping warm.
