[at-l] Wet Foot of down bags

[Bob C." <ellen@clinic.net (Bob C.)]

"...I  am  still  somewhat puzzled, since the foot of the bag can get rather wet
even when the inside walls of the tent are dry." reports Rick.

The  human  body,  regardless  of  whether  visible  sweat is present, is always
releasing  water  vapor.  When  that  vapor  hits  the  cold  wall of a tent, it
condenses  into water. It's the same phenomenon that causes the water vapor in a
room to condense into water when it hits an icy water glass.

The  phenomenon  seems  more  obvious with down, because down absorbs water more
readily  than  synthetic  insulations.  The same moisture is present. It just is
less noticeable to the touch.
