Simple, tough, and reliable, the Domex Mummy Polyester Liner is a versatile addition to your sleep system. Use it on its own during warm summer nights, or inside your sleeping bag for extra warmth and cleanliness. Shaped to comfortably contour a mummy-style sleeping bag, the liner reduces excess fabric bulk while providing a smooth barrier between you and your bag. This helps extend the life of your sleeping bag, keeping it fresher for longer on hunting trips, hikes, or backcountry missions. Made from durable polyester, the liner is lightweight, breathable, and quick-drying, so it’s ready to go again after an easy wash. Compact enough to tuck into any pack, it’s a no-fuss essential for campers and adventurers who want comfort without compromise.
