The Western Mountaineering HotSac Vapor Barrier Liner works by stopping heat loss from evaporative cooling and is a must have for technical winter outings. It also preserves the loft by keeping your body vapor from degrading the down insulation during extended stays inside your bag.

 

The Western Mountaineering HotSac Vapor Barrier Sleeping Bag Liner takes it one step further by stopping radiant heat loss with the reflective metal coating on the inside and an elastic draw cord that cinches around the neck. It weighs a mere 4.5 ounces and makes for an excellent emergency bivy on day trips.

 

Made right here in the USA.  Find out more about Western Mountaineering here.
