Sleeping bag liner for mummy sleeping bags and travel

The COCOON MummyLiner in microfiber is a lightweight mummy-shaped sleeping bag liner, designed as an extra inner layer in your sleeping bag or as a thin sleeping solution in warm weather. Thanks to its tapered shape, it fits well inside a mummy sleeping bag, helping you sleep more comfortably without unnecessary extra bulk.

This sleeping bag liner is also useful as a hygienic intermediate layer during treks, hut stays, hostel trips, or camping journeys. The blue version combines a compact packed size with low weight, making it easy to carry in your backpack or travel bag.

Microfiber for low weight and quick drying

The microfiber material is lightweight, breathable, and quick-drying. That makes this sleeping bag liner practical for travel, especially if you move around often or want to keep your gear compact. The fabric feels soft and is quickly ready for use again after washing.

For anyone looking for an easy-care sleeping bag liner, microfiber is a logical choice. The material takes up little space and is suitable for travel, summer camping nights, and use as an extra lining in your sleeping bag.
