Cocoon's vapor barrier liner surrounds your body with an ultralight, 100% non-breathable 15 denier Ripstop nylon shell laminated with TPU film inside. Ideal for long winter trips in extremely cold conditions, the technical lining minimizes heat loss through evaporation and reduces dehydration. The Cocoon Barrer helps maintain the insulation and loft of your sleeping bag by protecting it from body moisture. The vapor barrier liner also makes an excellent emergency bivouac shelter.
