Winter has become the only season I'm not swamped with TU projects or guide trips, so I find myself fishing often in the cold weather. Doesn't matter if I'm fishing, skiing, or hunting, I pretty much dress the same way. Depending on temps, at least one or two layers of long johns top and bottom and always moisture wicking materials. Sometimes I wear 3 layers with the outer most layer "Ploar fleece". Then I wear something over that accordingly. That is often regular blue jeans for fishing or ski pants or camo hunting pants if I'm doing those things instead. A coat of some sorts and my waders. I try to get away with a single pair of heavy socks, again, moisture wicking. If it's really cold, I may add toe warmers inside my waders. I wear half gloves that have a mitten cover up. The top mitten portion folds back and out of the way and the glove part only covers half my fingers, leaving me able to tie flies, mend line, etc. I'm usually so warm from the other clothes that I seldom even wear the gloves at all. Add a warm hat (again, moisture wicking) and you're all set. Waders keep out the wind as does my final layer which is typically GoreTex. And GoreTex breathes, so your sweat will not make your body get wet and clammy/cold. I add a neck gaiter if it's real cold as well.
