Brave the cold with confidence in our RedHead® Snowmachine Insulated Pac Boots for Men. These RedHead boots boast a class-leading -40°F comfort rating for the kind of extreme-weather performance you have to feel to believe. Powerful 400-gram 3M™ Thinsulate™ Insulation brings top-tier warming power without the weight or bulk of traditional men's insulated boots. 100% waterproof bottoms and innovative 8mm ethylene vinyl actetate (EVA) mid-layers block the cold from the ground from conducting up through the boot to your feet, giving you even more barriers against the cold. 10mm padded, removable liners enhance underfoot comfort, and the 15" high with nylon uppers shield your ankles and provides great coverage.
