Cocoon Mummy Liner

While temperature ratings vary by individual, this microfleece liner typically adds several degrees of warmth to your existing sleeping bag system. It is designed to trap body heat effectively, making it a solid choice for extending the comfort range of a three-season bag into cooler shoulder-season nights.

Yes, the liner is designed to function as a standalone bag for warm-weather camping. Its mummy shape, full-length zipper, and drawstring hood make it a comfortable, lightweight option for hut trips or hot summer nights where a full sleeping bag would be overkill.

Absolutely. The dual-texture microfleece features a soft, brushed interior that feels cozy and gentle against the skin, while the exterior remains smooth to help it slide easily into your sleeping bag.

While it follows a tapered mummy profile to maximize thermal efficiency, the inclusion of a boxed foot design provides extra room for your feet. This prevents that cramped feeling often associated with traditional mummy bags.

The liner is machine washable, which makes maintenance straightforward. We recommend washing it on a gentle cycle with mild detergent and air drying it to preserve the integrity of the microfleece fibers.

It is designed to fit most standard mummy-shaped sleeping bags. At 86.6 inches long and 31.5 inches wide, it offers a generous fit, but you should check your sleeping bag's dimensions to ensure it won't bunch up inside.
