The Ultralight Cotton Mummy Sleeping Bag Liner is the compact, lightweight sleep upgrade that earns its place in every pack. At just 360g and packing down to a tiny 19 × 9 cm, it adds warmth and hygiene without adding meaningful weight. The cotton fill delivers soft, breathable insulation rated for 5°C to 15°C — ideal for spring, summer, and early autumn use as a standalone bag or as a liner inside a heavier sleeping bag for colder conditions.
At 200 × 80 cm, it fits adults up to 1.8 m comfortably. The mummy cut keeps the liner in place throughout the night, and the splicing zipper lets you connect two liners for a double configuration when you need more space.
