Sleeping bag liner Sea to Summit Expander Liner Mummy

Soft inner sheet for sleeping bag or travel

Extends the life of your sleeping bag by keeping it clean.

Made from a pleasant, stretchy cotton/polyester blend. Cotton is a natural material that feels good on the skin, but the added polyester dries quickly, preventing moisture build-up.

The antibacterial treatment prevents the formation of unpleasant aromas and does not wash off.
