BDU pants, gore-tex boots, layers up top starting with poly pro, a wool shirt, topped off with a heavy wool insulated shirt, and I'll bring a rain jacket that I'll keep in my backpack but usually I won't pull it ou I always have a spare set of clothes in the truck for me and the boys.

I just know I'm going to get wet hunting if it is raining, so with the wool and the polypro, I stay warm even when wet.
