ALPS Mountaineering Mummy Liner Sleeping Bag

Sleeping bags are difficult to wash and dry properly, and frequent cleaning can degrade the insulation over time. This liner acts as a barrier that absorbs your body oils, sweat, and dirt, allowing you to wash the liner instead of the entire sleeping bag.

Yes. The brushed polyester material is breathable and lightweight, making it a great standalone option for warm-weather camping when a full sleeping bag would be too hot.

This liner is designed with a mummy shape that fits most standard mummy-style sleeping bags. At 86 inches long and 32 inches wide, it provides ample room for most campers, but it is best suited for bags with a similar tapered profile.

Not at all. Because it is made of brushed polyester, it is fully machine washable. You can simply toss it in with your regular laundry after a trip, making it much easier to maintain than a down or synthetic sleeping bag.

While it is not temperature rated, the liner adds a thin layer of fabric that can provide a slight boost in thermal comfort. However, it is primarily designed for hygiene and gear protection rather than significant insulation.
