The answer is VAPOR BARRIER. This is an air-proof bag you use inside
the sleeping bag to keep it dry from perspiration. In extreme
coldness the sleeping bag frozes within minutes and any moisture just
cannot get out.

Of course there is slight discomfort sleeping (preferably naked) in
your own sweat. Propably not very good for Brian who seems abhor his
own stench above all.

Vapor barrier bag liners make a great deal of sense in well below
freezing temps.

Good technical description at www.warmlite.com, specifically:

when viewing this site)

Many prefer a light layer of synthetic long undies inside a VBL, but
that is personal preference.

Yes, it gets a little funky, but if you are that concerned with
smelling pretty, winter camping (or any camping) may not be for you.

Happy trails,
