Sleeping bag liner for mummy sleeping bags and travel

The COCOON MummyLiner is a lightweight mummy-shaped sleeping bag liner made from 100% Egyptian cotton. This shape fits well inside a mummy sleeping bag and is useful when you want an extra sleeping layer for more comfort and hygiene while camping, travelling, or staying overnight in a mountain hut or hostel.

Thanks to the soft cotton, the fabric feels pleasant against the skin. Egyptian cotton is known for its fine, long fibres, which keep the liner light and compact without compromising on comfort.

Comfortable extra layer in warm and cool conditions

You can use this liner as a standalone sleeping solution in warm weather, or as a lining inside your sleeping bag when you want to keep your sleeping environment just a bit more comfortable and cleaner. The mummy shape helps provide a close fit, while the hood with drawcord gives extra protection around the head area.

The fabric is breathable and suitable for trekkers, campers, and travellers looking for a lightweight and easy-to-carry sleeping solution. It is also a practical choice in mountain huts, youth hostels, or for overnight festival stays.
