The Science of Staying Warm in Extreme ColdThe primary function of this vapor barrier liner (VBL) is to drastically reduce evaporative heat loss, one of the most significant ways your body gets cold during the night. The COCOON Vapor Barrier Liner surrounds your body with an ultralight, 100% non-breathable 15 Denier Ripstop Nylon shell that is laminated with a waterproof TPU-film on the inside. This impermeable layer prevents your body´s warm, moist air from escaping and cooling, effectively creating a personal microclimate that traps precious warmth next to your skin. By minimizing evaporative heat loss and reducing dehydration, this technical liner helps you stay warmer and more comfortable through the longest, coldest nights. Protect Your Most Important InsulationBeyond personal warmth, the Vapor Barrier Liner plays a crucial role in maintaining the performance and longevity of your sleeping bag. Over the course of a multi-day trip, body moisture can slowly seep into your sleeping bag´s insulation, especially if it´s down. This moisture compromises the insulation´s ability to loft, drastically reducing its thermal efficiency and leaving you vulnerable to the cold. The VBL acts as a shield, protecting your valuable sleeping bag from this internal body moisture. This ensures your insulation stays dry, lofty, and performing at its peak, night after night. It also makes a great emergency bivy, offering critical protection from wind and rain in an unexpected situation.
