When my goretex pants failed to stay dry in the Hoh Rainforest,
I found that rubber bibs OVER the goretex worked well. The
insensible sweat made it out through the gore pants and the
rain didn't penetrate the rubber overpants.

In a similar fashion, when rain eventually soaks through my
Goretex Hunting Coat, a light DriDucks jacket UNDERNEATH
helps keep my under garments dry and the fragile DriDucks jacket
is protected from brush pokes.
