An object in motion tends to stay in motion, and an object that's cold tends to stay cold, so it's important to make sure your hands don't get chilly in the first place. The Arc'teryx Anertia Women's Gore Tex Women's Mitten does the trick, with strategically placed Primaloft insulation and a waterproof Gore Tex XCR membrane that makes sure your fingers stay warm and dry when you're skiing storm day powder or hiking for turns outside the resort boundaries. XCR is also highly breathable, so sweat won't build up when you're farming springtime corn, and it works in concert with the Fortius 1. 0 softshell to make sure that your hands stay dry in all conditions. A tough, pre curved leather palm makes it easy to hold on to ski poles and fight your way through trees, and the Anertia's hook and loop cuff makes sure no snow sneaks into your mitt and freezes your fingers.
