Frequently Asked questions

Does this sleeping bag liner fit regular and wide sleeping bags?

This liner is made with durable stretch fabric so it can fit in any sleeping bag shape and you won't even notice.

Does the sleeping bag liner have a zipper?

No. In order to keep this sleeping bag liner at a minimal weight and packed size we did not include a zipper.

Is the sleeping bag liner machine-washable?

Yes! This sleeping bag liner is machine-washable for ease and convenience. You can wash your liner with laundry detergent and machine dry, using cool or low heat. Steer clear of fabric softeners, though, since they tend to reduce wicking performance of the fabric.
