Instead of using a Vapor Barrier Liner (VBL) bag to keep my winter bag dry I'm using a very light urethane coated and seam sealed rain suit.
The reasoning is that this suit will allow me to wear insulating clothes like my light down jacket over it and keep the insulating clothes dry. Sleeping bags sometimes need the help from a layer of insulating clothes to sleep comfortably through the night if a cold front pushes in unexpectedly.
My (very) heavy -20 F. Mt'n hardwear polarguard bag has a nice feature I see on very few other winter bags, namely a full length side zipper that reveals a 6" wide insulated expansion panel just above the main zipper.
In trying out this combo the -20 bag will easily accomodate my WM Megalite 30 F. down bag if hell ever freezes over.
