Lifeventure Thermolite® Sleeping Bag Liner – Add Warmth Without Extra Weight

Lifeventure Thermolite® Sleeping Bag Liner is designed for hikers, trekkers, campers and travellers who want to improve sleeping comfort while extending the performance of their sleeping bag. The premium Thermolite® insulation fabric traps warm air efficiently while remaining lightweight, breathable and highly compressible.

Whether you're camping in cooler conditions, travelling through different climates or staying in hostels, this liner provides additional warmth, improved hygiene and greater sleeping comfort.

Boosts Sleeping Bag Performance

The Thermolite® fabric can increase the warmth of your sleeping bag by up to 15°C, depending on your sleeping bag, clothing and environmental conditions. This makes it an excellent solution for extending the comfort range of an existing sleeping bag without purchasing a heavier winter model.

Soft, Stretchy & Fast Drying

The lightweight fabric feels soft against the skin while allowing unrestricted movement during sleep. Excellent moisture-wicking properties help transport perspiration away from the body and the material dries quickly, making it ideal for multi-day adventures.

Polygiene® Odour Control

Integrated Polygiene® odour control technology helps prevent the growth of odour-causing bacteria, keeping the liner fresher for longer and reducing the need for frequent washing during extended trips.

Versatile Outdoor Companion

The liner can be used inside your sleeping bag for additional insulation or on its own during warm summer nights. A built-in drawstring hood improves heat retention around the head, while the included tough ripstop carry case protects the liner during transport.
