The opinion of Aventure Nordique
Using a vapor barrier liner with your sleeping bag can save your life. During extended trips in arctic conditions, even the best bags can get damp and heavy from accumulated body vapor. A vapor proof liner like the VBL-Linerbag UL will help to preserve insulation because the insulation is not contacted by potentially freezing perspiration. VBL-Linerbag UL also functions as an emergency, waterproof bivy sack.
