As for gloves and mittens, I don't like gore-tex, dries out my hands too much. Leather with real or fake wool lining is good, but I usually wear a light mechanics utility glove, (not the one with velcro) inside a heavy pair of wool lined leather chopper mitts. If I have to take the mitts off, I still have the glove for protection. At 25 below or colder, if you touch metal with bare skin, you get frostbit on your hand or fingers. I went out and pushed the shed door closed last night. In doing so I touched the hasp on the door, felt like I had touched a red hot poker. Today I have a sopt on my finger that looks like I had touched something hot and burned my finger.
For just everyday running around, I wear Sweat pants under Arctic Insulated Carhart Bibs. A mock tee or a sweat shirt under a wool sweater, and usually a Columbia Wool Jacket, with a Heavy Goose down vest over the jacket. Wool socks, inside one size too big extra wide sneakers A coyote fur bomber style hat.
Dressing for 45 below or colder: Cotton briefs and tee shirt, poly thermals just don't stay in place enough, and they dry out my skin. Polypropoline thermals, they wick any moisture out of the cotton and away from your body. Wool Socks, calf or knee high. Wool or poly shirt and pants. Wool sweater. Columbia wool jacket with hood, with Cabela's heavy goose down jacket. (I like the Columbia jacket because it's wool and iot has shell holders sewn into the pockets). Or a heavy Carhart arctic insulated jacket with hood when it's really cold, 65 below or colder. Or there is little chance of getting wet. Arctic insulated Carhart Bibs. A Coyote fur bomber style hat to keep my ears and head warm. Nothing keeps you as warm as real fur. A neck warmer or a Balacava to keep my neck and face warm under the hat. Wool mitten liner or glove inside leather mittens. And last of all my Bunny Boots. Bunny Boots are made out of rubber. They are white, and big big boots. Heavy too, but they are the only thing that will keep your feet warm down to 65 below. Once you have worn them when it is extreamly cold you will want nothing else. And a face mask. In an emergency duct tape will work, but a face mask is best.
