I'm on the opposite end of the spectrum. I sweat *a lot*, and need something that breathes really well. If it doesn't breathe well, I feel hot and wet, or worse, cold and wet To some extent, you do get what you pay for in this area. You don't have to pay a fortune to be reasonably comfortable - something like a Marmot Precip on sale isn't too expensive and does a reasonable job. Gore-Tex is more breathable, or, even better, something made with Event.
By the way, there are definitely some clean folks on this board. I'm lucky if I wash my coat/jacket once a year. Maybe that is why I'm having trouble finding fishing buddies .
