The Sea to Summit Expander Double Liner is made from super stretchy fabric that makes it ideal for use in double sleeping bags. It moves with you as you sleep so you and your partner won’t have any battles over who is hogging the sheets.
The soft poly-cotton fabric is nothing super lightweight or technical - it’s just warm, comfortable and easy to clean, and what’s more, it won’t cost more than the sleeping bag it will be used in.
Made with an anti-microbial treatment keeps your liner hygienically odour free and does not wash out of the liner, the Sea to Summit Expander Liner is the most comfortable and affordable way to keep your sleeping bag clean whilst adding warmth and comfort to your sleeping arrangements.
What a great addition, a stretchy warm liner and no getting twisted up in the night. We used it in sub zero temps and it was excellent.
We sleep inside our 4wd and or mattress is darche atm1100.
You sure can use the liners on their own but I'd only recommend it on a warm night as they don't provide a great deal of warmth when used on their own.
