The Sea To Summit Reactor Thermolite Liner is made from the hollow core fibre, Thermolite, which provides exceptional warmth for its weight. As a result it adds up to a further 8 degrees C to the warmth of a sleeping bag. This makes it ideally suited for use as part of a cold climate sleep system, or on its own in warmer climates as a standalone lightweight bag. The Reactor Thermolite Liner is odour resistant and machine washable for ease of care.
