High-altitude climbing calls for high-tech gloves to ensure our hands return with all their fingers. The Mountain Hardwear Absolute Zero GORE-TEX Down Mitten ensures warm, dry, and cozy hands and fingers all day thanks to its heavyweight insulation and GORE-TEX waterproof membrane. The Absolute Zero GORE-TEX Down Mitten is filled with 800 fill-power goose down, topped off with a cross between Aerogel technology and Primaloft Gold synthetic insulation to eliminate any cold spots, and finally, a heavyweight polyester fleece lining adds the final layer of warmth. The Absolute Zero Mittens have a Pertex Diamond Fuse ripstop nylon shell and a Pittards goat leather palm for optimal durability and abrasion resistance, and the gauntlet-style cuff has a wrist strap and a drawstring closure for security.
