Long johns, jogging pants, outer pants of choice. T shirt, sweat shirt, jacket of choice. That’s most of hunting season, in a tree stand. If really cold break out the Duxback bibbs, and big jacket.
If below 20 degrees, I wear first choice and take a sleeping bag in with me. Take off my boots and slide into that sleeping bag. Stay warm all day
Running deer dogs, pants and sweat shirt, usually briar chaps as well. No matter how cold really. You can move around deer dogging and stay warm.
