Extreme weather demands extreme gear, and the Hestra Army Leather Extreme Mitts will be your best friend on those days when the wind is blowing a little harder and the snow is turning into freezing rain halfway through the day. Hestra's Army leather was originally designed for the military, let's hope the conditions on the mountain aren't quite that extreme, and they have used extra Army leather in some common areas for wear on the Extreme Mitts so that they will stand up to years of abuse. The flexible 4 way stretch fabric throughout the rest of the mitten moves with you and keeps the insulation closer to your hand. The warmth however, is the bragging point of the Army Leather Extreme Mitts, as they are one of Hestra's warmest options for winter enthusiasts.
