Mr. Lizard-
If you are having trouble with your breathables drying trying treating them with Revivex. Revivex brings back the water repleccent in Gore-Tex and other breathable fabrics.
If it very easy to use and your waders will almost surely dry much faster.

CnD-
I have heard similar reports inregards to the SSTs and DEET but I have not heard any detailed reports in regards to the severity of this problem and what Patagonia's customer service does to rectify the problem.
