The people of Yellowknife, Canada, know a thing or two about cold – and their occasional sighting of an Arctic fox wandering around downtown is proof. For working outside in cold like that, you need our warmest winter mitts. Waterproof and breathable, they have a tough, flexible 93% nylon/7% spandex shell reinforced with rugged goatskin that stays supple even if you get it wet. Inside, we’ve paired up lofty insulation and a soft polyfleece lining with extra-plush sherpa fleece at the back of the hand for amped-up warming power. "Trigger" design lets you comfortably operate a nail gun in the freezing cold. Pull-out fleece liner acts as a lighter-weight glove when you need more dexterity. The finger pads are touchscreen-friendly, so your fingers don’t get frost-nipped if you need to answer your phone.
