Under Armor cold weather long sleeve shirt, 2 pairs of sweatpants, 2 sweatshirts, thick socks, outer layer pants and coat. Rubber boots keep my feet warm. They are 1200 gram. I also have a hand warmer that you buckle around your waist. I still wear some thin gloves, but this really keeps my hands toasty. I also usually keep my hat off until I really start to get cold. Otherwise, I tend to sweat pretty easily. I believe that your head is almost the "thermostat" of your body. You can usually warm yourself up or cool yourself off by your dome.
