Sea To Summit Thermolite Reactor Sleeping Bag Liner Mummy

Sea To Summit Thermolite Reactor Sleeping Bag Liners are the perfect hygienic layer for adding extra warmth without unwieldy bulk.

Manufactured from 80g/ m² Thermolite®polyester fabric, these liners are super stretchy, soft and comfortable, with a tapered mummy shape, foot box construction and a drawcord hood. The hollow core fibers that make this fabric so lightweight also enable it to trap body heat, increasing sleeping bag temperatures up to 8°C. 

When not in use, these thermal sleeping bag liners pack away compactly in to a tough ultra-sil stuff sack.
