Add to the wool, a wool Cabelas wind stopper sweater and you are set! I also have a pair of wool bibs, with the sweater and bibs all I need is my base layer and maybe a sweatshirt and pants.
Wool mittens I can peel back to expose my fingers and a face mask are also staples.
Couple of years ago I bought a pair of Muck Boots, they are for duck hunting but they sure keep my feet warm.... with again WOOL socks.
Get it????????? Wool and more wool..........
