Description
The Sea To Summit Reactor Extreme is a compact sleeping bag liner made with heavy weight Thermolite fabric (110g/m²).
The spacious design is tapered slightly to save weight and increase thermal efficiency, it also has a drawcord hood which can be cinched down when you really need all the warmth you can get. As it is made from a knit fabric it does have a good amount of stretch which means you'll be more comfortable moving in it when you sleep.
Thermolite is a hollow core fibre providing a high warmth to weight ratio while remaining extremely breathable. The Reactor Extreme will add up to 15°C to a sleeping bag's warmth. Lighter and more packable than fleece, in warmer weather the liner can be used on its own as a super light sleeping bag.
