It's not just your own body producing sweat that makes them work. They
also rely on the material wicking away moisture--or being dry at the
With a vapor barrier, if you start out too wet, you won't
dry--especially when it's extremely humid.
So, I'm not convinced vapor barriers work under rolling fogs, typhoons,
and other extremely humid conditions--all are damp, cold, and
The Appalachian Mountains have often been called a Temperate Rain
Forest. In Taiwan at the elevations where I hike (2000-3000 m), the
mountains are Temperate Rain Forest, too. Because the ambient humidity
is so high, Taiwan's hikers tend to carry down bags rated for much
colder temperatures than expected. This is because the humidity
permeates everything and affects loft. Under these conditions, damp
clothes, if slept in, usually do not dry. So, I make sure I pack
sleeping clothes (including socks) in the same bag as my sleeping bag
and I change into these clothes right before bedtime.
