Since I don't actually hunt in the driving rain, but just need raingear to get me through downpours etc., I end up carrying rain gear a lot more than using it. Like Jimmy C, another vote of confidence here for the Cabela's Space Rain packable stuff. Works great and mainly it's very light and compact, which means it's in my pack when I need it. Tippit used mine at last years bear hunt and came back with the testimonial of "I'm buying some of that stuff!".
I'll agree with Gnat too, the arc'Teryx stuff is superbly built....if I hunted frequently in torrential downpours or in an area that had more rain than sun, I'd consider a set of these. I know more than a few serious backcountry expeditioners who wouldn't trade theirs for anything.
