If your sleeping system needs some extra warmth, then the Thermolite Reactor Liner from Sea to Summit will add up to 8°C and help keep your sleeping bag clean.
This liner is made from Thermolite hollow core fibres which traps heat and has excellent insulating properties while being lighter than fleece. Thermolite is also soft and super stretchy so it’s really comfortable. The design of this liner is optimised for warmth, as it has a mummy shape, footbox and a drawcord hood. It will add up to 8°C of warmth to a sleeping bag, or it can be used on its own as the ideal warm-weather bag. The Thermolite Reactor also comes with a stuff sack included, so you can store it away neatly when not in use.
