Just so all the choices are covered - all of my hunting season is cold and snowy. I'm not attracted to any of the new clothing. I like the heavy wool pants and have woolrich. Lately the replacements are some out of Canada. The big legs give me room to move without being bound up. I have woolrich shirts that have lasted over 20 years. I recently have had to bolster up the pockets.
I like duofold long johns. They kept me warm for years. I have worn army surplus wool calvery coats (tough to find) for an overcoat and lately have used an orange pumpkin coat out of Minnesota for riding. I keep it on the horse. I can put it on when I am sweated out after a long hike and I will be warm and dry by the time I get back to the truck.
I also wear elkhide batwing chaps to protect my legs and keep them warm while I am riding. All the limbs and downfall sticks are all tough on clothing and tack as you ride through the trees. I make all of those from elk I kill.
On the really cold days, I wear military surplus coat liners. They are cheap and durable. Not exactly a fashion statement. Just durable clothing that gets me through -10 to -20 degree days without discomfort.
Army surplus arctic mitts have been my go to since 1971. Gloves don't hack it. Hats range from beanies for hiking, fuzzie hats for riding to ball caps on the warm sunny days.
