RvW any woodlands or green based camo will be perfect. As for waterproof material that breathes...Gore Tex is the top dawg there. Lots of companies make Gore Tex fleece which is nice stuff. Saddle Cloth is good stuff too but doesnt breathe too well. Wool keeps you warm but I hate hunting in it.
I'd go to a surplus store and get a solid pair of woodlands BDU's for pants, then a buy a nice gore tex fleece sweatshirt.
Getting a little wet makes you hunt harder!
