The opinion of Aventure Nordique
The Vapor Barrier Linerbag UL from Exped is a vapour barrier for sleeping bags. It is the ideal accessory for protecting the interior of down sleeping bags.
The main drawback of down is that it stores moisture, which reduces its thermal performance. In very cold temperatures, body moisture tends to condense. After several days, if you have not managed to dry the down, the thermal performance of your sleeping bag will be reduced.
To avoid this inconvenience, the Exped VBL Linerbag UL comes into play: it blocks body vapour and completely stops condensation. Moisture remains inside the VBL and does not accumulate on the walls of the down.
This vapour barrier system is particularly effective for long expeditions where the insulating power of the sleeping bag must remain the same day after day.
The VBL Liner is reasonably lightweight at 125 grams. With equal insulation, the combination of a goose down sleeping bag and a VBL Linerbag is much lighter and more compressible than even the most high-performance synthetic sleeping bag on the market.
It is advisable to sleep in long underwear or in a sleeping bag liner to avoid direct contact with the VBL and increase your comfort. The VBL provides a few extra degrees of warmth.
