Sea to Summit Thermolite Reactor Extreme Mummy Liner

The Sea to Summit Thermolite Reactor Extreme Mummy Liner is S2S' most insulating sleeping bag liner, increasing warmth by up to 15°C. The construction is tapered from head to foot, like a mummy sleeping bag, to decrease volume and improve thermal efficiency, and the internal drawcord hood can also be tightened, like a mummy sleeping bag.
