I dress in lawyers and my outer layer is the Cabela' s insulated silent sued overalls and jacket. The Maine woods get VERY COLD Thanksgiving week and since I purchased these 2 pieces I am no longer cold. Oh and I have a pair of RedWing 1000 gram thinsulate tracker boots. Glo-mitts for the hands (mittens that fold over) so you can hold the gun with your hand with a pair of insulator gloves on first. And last but not least is a fleece head cover, the one that can be worn several different ways. I bought every thing so I can sit on stand in the coldest of conditions and not shiver.
