The Sea To Summit Reactor Midweight Liner is sleeping bag liner made from a blend of Thermolite Pro with Far Infrared (FIR) technology and hollow-core fibres. Thermolite Pro has engineered hollow fibres and ceramic pigments that absorb the body's infrared rays and reflect them back to the wearer. The HeiQ Fresh odour-control treatment helps it stay fresh during extended trips, while reducing how often you need to wash your sleeping bag—helping maintain loft and extend its usable life.

The Reactor liner will provide a 6°C warmth boost to a sleeping bag.
