The enemy: heat loss. Your offense: the women\'s Burton GORE-TEX Warmest Mitt, powered by 550 fill, responsibly-sourced down and Thermacore insulation, all housed in waterproof DRYRIDE 2L fabric. The DRYRIDE membrane adds an extra measure of waterproofing and breathability and curbs wind and water, and zaps sweat. The brushed microfiber fixed lining flips the bird to subzero temps. When the pow stacks up, Burton-exclusive Screen Grab® tech built right into the leather lets you text your boss: \"Too sick to work…\". Without having to expose your hands to the cold.
