Rab Hooded Vapour Barrier Liner

"The fact that your sleeping bag keeps you warm even in extreme cold is thanks to the fully vapor-proof hooded sleeping bag liner. The ultra-lightweight fabric with water-repellent Silcoatu2122 and DWR coating prevents moisture from penetrating from the body into the down of the sleeping bag. This protects the down from condensation and freezing, even at sub-zero temperatures, while retaining its loft and warmth. The contoured hood can be cinched tight around the face with a drawstring and stowed compactly in its own integrated mesh bag. With a tare weight of just 180u00a0g and its small pack size, it is perfect for longer expeditions in Arctic regionsu00e4."
