This ultralight liner prevents moisture from the body getting into the down in your sleeping bag. Perfect for expeditions to extremely cold climates.

The Hooded Vapour Barrier Liner is a clever bit of kit to be used inside your sleeping bag in extremely cold temperatures. The ultralight fabric has been treated with a Silcoat™ water resistant finish and a DWR, and prevents moisture passing from the body into the down of your sleeping bag. This protects the down from condensation and freezing, maintaining its loft and warmth in sub zero temperatures. It has a contoured hood with draw string so you can cinch it in close around your face and an integrated mesh stuff sack for packing down small. At just 180g, it’s perfectly packable for extended expeditions to very cold climates.
