Congratulations, you made the right step out from the miserable
clueness this thread was stuck into.

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.
