I think I will give the duofold a shot first. When I hunt I either sit and watch trails or still hunt. I'm never more than an hours walk from the truck, or deer camp. My other hunting garb consists of Codet melton wool pants and vest, a Woolrich plaid shirt, and a wool mackinaw coat. I have hunted in this wearing boxers and a t-shirt underneath before, but I think the slight added warmth of the duofolds will make things a little more comfortable when I am sitting still for long periods. If they don't work out I'm not out much and I can always get the all-wool ones later.
