Sea to Summit Reactor Lightweight Liner – Regular

Upgrade your sleep system with the Reactor Lightweight Liner, engineered to add warmth without the bulk or weight. Thermolite Pro far infrared fibre technology enhances warmth by trapping insulating air in hollow-core fibres and reflecting your body heat back to you using ceramic pigments, boosting your sleep system by up to 4°C and making the Reactor series the first choice for cool-to-cold weather sleep systems.

The stretch-knit construction with armholes and snap closures allows complete freedom of movement, so you can toss and turn comfortably through the night. Quick-drying and easy to clean, with HeiQ Fresh odour control, the liner keeps you fresh on extended trips while protecting your sleeping bag from frequent washing and extending its lifespan. Compact, lightweight, and compatible with any sleeping bag, the Reactor Lightweight Liner also snaps into Sea to Summit bags for effortless entry and exit, making it the ideal companion for lightweight adventures.
