What Our Gearhead® Experts Are Saying: "This liner is insanely warm for the weight. The grid-pattern Thermolite fleece traps heat really well, and the shoulder zips plus drawcord footbox make it easy to regulate temps. I’ve used it to push a lighter bag deep into shoulder season—and as a standalone in warm weather. Super versatile." We reach for the Sea to Summit Reactor Fleeceweight Liner when temperatures dip and our sleep system needs serious reinforcement. Built from hollow-core Thermolite EcoMade fibers arranged in a heat-trapping grid pattern, it’s the warmest liner in the Reactor series and the foundation of a dependable cold-weather setup.
