Costco always seems to have something that will work for hunting pants. Gerry fleece lined pants were great, but I haven’t seen them in a few years. I love the Costco merino blend socks.
Big guy here, 6', over 200. I find the Duluth pants and the Orvis Pants have both been excellent.
Orvis I have not found the difference between in store vs Costco, although I know people claim they are. They both wear the same to me, I have bought both.
Duluth are just comfortable.
