RE: [pct-l] Why sleeping nude in a sleeping bag makes us feel warm.

["Ted Rupp" <ted@nidlink.com>]

I would also point out that the moisture factor comes in a second way.  If
you wear the same clothes to sleep in that you hiked in, there is residual
moisture in those clothes.  Sleeping in clothes may dry them out but that
moisture from the clothing is absorbed by the sleeping bag insulation,
whatever it may be (down or synthetic).  This results in a gradual loss of
insulating ability and may result in warmth problems several days into the
trip, especially in winter.

Obviously this problem is avoided by using a Vapor Barrier Liner in the
sleeping bag.  No Moist reaches the insulation from your body or your
clothes.  But if you wear your clothes in the VBL, then they will be wet
when you wake up in the morning.  If there is no VBL, you are probably
adding residual moisture to your sleeping bag insulation = heavier bag and
less warmth (especially with down)

IMHO
