Description

Upgrade your camping setup with the Sea to Summit Reactor Sleeping Bag Liner. Designed for backpackers who need extra warmth without the bulk, this mummy-shaped liner uses Thermolite Pro fabric to provide a significant thermal boost. It is an ideal solution for enhancing a 1-season bag or adding extra insulation to a 3-season bag during colder conditions. This liner features infrared technology and stretchy fabric to ensure exceptional comfort and better insulation compared to standard fleece options. The technical mummy shape includes a drawstring hood for a snug, secure fit inside your sleeping bag. When your trip is over, maintenance is simple as the liner is machine washable and requires no special soaps. Compact and lightweight at only 284g, it comes with an Ultra-Sil stuff pack, making it easy to carry in your pack. Whether you are trekking through mountains or camping in the woods, this liner helps you stay warm and comfortable while keeping your gear clean and organized.
