Mountain Warehouse has a choice of sleeping bag liners in silk, microfibre and polycotton to enhance your warmth and comfort inside your sleeping bag.

Sleeping bag liners work in the same way as a bedsheet on a mattress, and help keep the sleeping bag clean and increase its longevity. They are especially useful when using a sleeping bag for an extended period of time, or when borrowing someone else’s bag, even when you are at a muddy festival and cleaning yourself isn’t all that simple; you will find a sleeping bag liner is easier to clean and much easier to wash than a sleeping bag. In warmer weather, you can even sleep just inside the sleeping bag liner.

Our sleeping bag liners comes in both the mummy and rectangular shapes to fit inside whichever sleeping bag you own, and are soft to enhance your comfort. All of our liners are lightweight and come in their own stuff bag for easy transportation and storage. A sleeping bag liner will also increase the temperature rating of your sleeping bag by up to 2° depending on the fabric you choose and silk liners can add a whole season, typically 5°. They are also ideal to keep handy when sleeping in a bed that isn’t your own, especially when travelling.
