Some of the warmest clothes I ever wore were the Surplus Swiss arm field pants I used when I first started getting serious about elk hunting. With just about any long johns under them I could sit in 2-3 feet of snow in single digit weather and wind and keep warm all day long. Hated to give up on them, but I "outgrew" them and never did find another pair that fit as well. Also, they were a bit warm for hiking around in those conditions....
