Sea to Summit Reactor Midweight Liner – Regular

Enhance your sleep system with the Reactor Midweight Liner, a versatile liner built for every adventure. Thermolite Pro far infrared fibre technology traps insulating air in hollow-core fibres and reflects your body heat back using ceramic pigments, adding up to 6°C of extra warmth, making the Reactor series a top choice for cool-to-cold weather sleep systems.

The stretch-knit design with armholes and snap closures offers complete freedom of movement, so you can toss and turn comfortably throughout 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. Compatible with any sleeping bag, it also snaps into Sea to Summit bags for effortless entry and exit, making the Reactor Midweight Liner the ideal choice for all campers and backpackers.
