Ultralight stretch sleeping bag liner

Sleep softer. Stay cleaner. Pack lighter.

Enhance your sleeping comfort with the Ultralight Sleeping Bag Liner, made for camping, travel and hotel stays. Its high-elastic, breathable fabric adds warmth, protects your sleeping bag and gives you a soft, silky touch against your skin.

Lightweight and portable, it is the essential companion for outdoor adventures: slip it inside your sleeping bag for a cleaner, cozier night, or use it on its own as a lightweight adult sleep sack on warm nights and hotel beds.

A cozier, cleaner sleeping bag

Make your sleeping bag feel like your own bed.

Slide the liner inside and every night out starts softer. It adds a nice layer of warmth and acts as a barrier between you and your sleeping bag, so the liner takes the sweat and the dirt and your bag stays fresh. When you get home, the liner goes in the washing machine instead of your bag.

Buyers feel the difference: “Adds a nice layer of warmth and keeps my sleeping bag cleaner.” (Rex E.) and “It made my sleeping bag so much more comfortable” (Rachel G.).

Silky stretch

Soft, stretchy and made to move with you.

Flat travel sheets bunch and twist as you turn. This mummy-shaped liner is made with 20% high-elastic fiber for a smooth, skin-friendly feel, and it stretches with every move, so you roll over freely. Its durable yet stretchable design ensures a comfortable fit for adults up to 5 ft 11 in (1.8 m).

The breathable material keeps air moving to prevent overheating in warm weather: “Soft and comfy!” (John P.) “Super breathable” (Jessica S.) “It doesn’t feel sticky like some liners do.” (Hannah R.)
