A very useful 6 oz. to extend temperature rating of Western Mtneering Antelope MF by maybe 10F. I really like how it keeps the down much, much drier, as it's a total pain in the fedunza to dry a bag in the winter. 

It probably could also double as a lightweight bivuoac sack.  Really like the VBL concept, hope soon to try a Warmlite triple bag.
