Western Mountaineering - Hot Sac VBL

Western Mountaineering's bright red Hot Sac VBL is a reflective vapor barrier liner designed for technical winter mountaineering. By surrounding your body with a non-breathable shell, evaporative cooling is prevented and you are able to remain much warmer. A VBL also protects your sleeping bag's loft by keeping your body vapor contained, and reflects body heat with its reflective metal coating, much like an emergency blanket. This is most important for extended trips in very cold weather.
