Cinch down the Backcountry GORE-TEX All-Mountain Mitten and break trail on powdery mornings, knowing that blustery snow has no chance of interfering with your warmth. We made the All-Mountain Mitten with GORE-TEX waterproofing for dependable protection from winter's weather. A grippy goatskin leather palm secures your hold on ski poles, and the gauntlet style covers your wrists from the elements.
