Alti Mitts are a household name among 8,000-meter climbers and Arctic expeditionists, and now, they've been redesigned with even better dexterity and fit. The warmest pair of mitts in our collection, the Alti II GORE-TEX Mitts use a modular design to create a layering system for your hands, ensuring warmth, durability, and comfort that will last on multi-day, multi-week trips in extreme conditions. Waterproof and windproof GORE-TEX outer shell provides durable protection from the elements, and a removable insulated PrimaLoft liner keeps your hands toasty. Plus, a glove clip and carabiner loop keeps these close at hand by attaching easily to your pack or harness.
