The Reactor Liner features a mummy shape and uses Thermolite® Pro fabric, incorporating innovative infrared technology and comfortable stretch fabric to provide enhanced warmth, versatility, and insulation. Equipped with a draw cord for added flexibility, it ensures premium comfort, making it ideal for cold conditions. Thermolite Pro fabric includes engineered hollow fibres similar to standard Thermolite material but with the addition of permanent ceramic pigments. These pigments absorb the body's infrared rays and then reflect them back to the wearer, contributing to improved warmth and thermal efficiency. The Sea To Summit Reactor Liner syncs perfectly with any sleeping bag, making it a must-have item for your next camping adventure.
