Sleeping in a sleeping bag liner protects your product and makes it easier to maintain your sleeping bag (less washing = better durability and thermal performance over time). It's very useful in huts and refuges. For improved comfort, choose a bag cover in the same shape as your sleeping bag.

Using a Forclaz silk bag cover helps optimise the thermal quality of your sleeping bag by approximately 1.5 to 2°.

Silk is a natural and fragile material. Be careful when you enter and get out of your sleeping bag to not expose the stitching to stress.
