Designed to add warmth without bulk, the Thermolite Sleeping Bag Liner is made from a lightweight, durable fabric that is soft and stretchy for a comfortable night’s sleep. It can increase sleeping bag performance by up to 15°C, making it ideal for cold conditions, shoulder-season camping or extending the range of your existing sleep system.

An integrated drawstring hood helps retain heat around the head, while Polygiene odour control technology keeps the liner fresher for longer. Suitable for use on its own or inside a sleeping bag, it packs away neatly into a tough ripstop carry case.
