About the Sea to Summit Thermolite® Reactor Extreme
The Thermolite® Reactor Extreme Liner delivers Sea to Summit's warmest backpacking sleeping bag liner. The minimalist design delivers a lightweight and practical way to add warmth to an existing sleeping bag across a range of pursuits; from backpacking to alpine trekking, winter camping and more.
Cosy Thermolite® fabric provides an excellent warmth-to-weight ratio with hollow core fibres working like the fur of a polar bear to trap heat effectively, boosting warmth by up to 14°c (dependent on conditions) while remaining breathable to wick heat moisture away from the body. The stretch fabric helps you settle into a comfortable position while a drawcord hood and footbox add comfort and temperature control.
The Thermolite® Reactor Extreme can be used on its own or as a sleeping bag liner to boost insulation in colder weather. Liners also help in keeping your sleeping bag cleaner and fresher for longer by reducing the build-up of dirt and oils. Great for a range of travel experiences, from alpine and backcountry tours to camping, backpacking and anywhere else you choose to roam. Now updated, the Reactor Extreme Liner uses new infrared technology paired with comfortable stretch fabric to offer extra warmth, versatility, and increased insulation.
The Thermolite® Reactor Extreme from Sea to Summit is a cold weather travel essential with assured quality.
