If you guys in the cold, that's like 10 degrees or less everything else is balmy, haven't tried Rocky Heavy Thermal long johns, give the Rocky heavy thermal under baggers a try. this stuff is great. warm, maybe even hot. I've been wearing it through deer season and i work outside a lot. been snowshoeing and this stuff is great. now if they only made socks. on a scale of 1 to 10 it would be a ten for comfort and warmth.
