Adding up to 8°C of warmth to a sleeping bag, the Sea To Summit Thermolite Reactor Mummy Liner is an excellent cold weather option for those who need additional warmth. Made from Thermolite® - a hollow core fibre that traps heat and provides amazing warmth for its weight while remaining extremely breathable. It's super soft, compact and lighter than fleece liners. Can also be used alone as a warm weather bag which makes the Reactor a perfect choice for both trekking and travelling.
