Think of the Mercury Mitt as an insulated cocoon for the hands—we’re talking about ultimate warmth here! Designed for mountaineering, boarding and all-weather skiing, the storm-worthy Mercury Mitt is 100 percent waterproof and packed with PrimaLoft. With an extended gauntlet that locks in warmth and keeps snow out, the Mercury is also equipped with a cinch-strap on the back of the wrist to seal in body heat. A breathable shell allows for moisture management, while the cowhide leather palm extends over the fingertips for added durability. A must-have mitt for anyone traveling in seriously chilly terrain. Temperature range: down to -20°F (-29°C).
