VBL SUIT:
In another thread I suggested wearing a "VBL (Vapor Barrier Liner) suit for sleeping to keep your perspiration from gradually wetting your down over several nights. A VBL suit will work, and well, but it brings with it the problem of drying the inside out every day.
SYNTHETIC FILL TOPPER:
An alternative to a VBL suit is the thin synthetic fill "topper" that goes over your down bag. The idea here is that most of your perspiration will migrate out of your bag until it reaches a condensation point temperature. Then this topper can be aired out daily and beaten to rid it of accumulated frosty moisture. It does work, just not as completely as a VBL suit.
But this topper will add perhaps 10 F. of warmth as well. extend your bag's temperature range.
Look at Thermarest for one of these as well as other backpacking companies. OR cut down a light, thin bedspread to make one.
