Sea To Summit Reactor Fleeceweight Liner Long

Reactor sleeping bag liners have been very popular for years. A liner dramatically reduces the need to wash your sleeping bag, and especially the Reactor models also provide extra warmth. Washing a sleeping bag is sometimes necessary, but it always wears it out to some extent – it’s much better to wash the protective liner inside the bag.

This model uses ThermoLite EcoMode material: among the hollow-core fibers that trap lots of warm air are fibers that wick away moisture. The Fleeceweight version is not the lightest liner on the market, but its estimated warmth boost to your sleeping bag’s rating is as much as +8°C.

Thanks to the upper section design, the liner allows you to bring out both hands when needed.
