Sea To Summit Reactor Fleece Sleeping Bag Liner

Add Warmth, Extend Your Season – Sea to Summit Reactor Fleece Sleeping Bag Liner in Red

The Sea to Summit Reactor Fleece Sleeping Bag Liner is the smart, versatile addition to any sleep system that adds meaningful warmth without the weight and bulk of a heavier sleeping bag. Crafted from a soft, cozy fleece fabric, the Reactor Liner adds several degrees of warmth to your existing sleeping bag — effectively extending its temperature rating and your camping season. It also works as a standalone sleep layer in warm conditions or in a hostel or hut where you'd rather not use the provided bedding. The vibrant red colorway is easy to spot in your gear pile, and the Regular size fits most sleepers comfortably. This is the sleep system upgrade that punches well above its weight.
