When the mercury drops and mountain conditions turn serious, the Arc'teryx Beta Down Mitten delivers the warmth and protection that can make the difference between a successful summit and an early retreat. Built around premium 750-fill European grey goose down and bombproof 2L GORE-TEX construction, these packable mittens punch well above their 120g weight class, providing exceptional warmth without the bulk that compromises your pack space or dexterity. The genius lies in Arc'teryx's Down Composite Mapping™ technology, which strategically places synthetic insulation in moisture-prone areas while keeping the ultra-warm down where it works best, ensuring your hands stay toasty even when conditions get wet and wild. Whether you're belaying on an alpine route, skinning up a backcountry peak, or simply need bombproof emergency hand protection in your kit, these mittens combine the technical performance serious mountain athletes demand with the packability that won't weigh down your adventures.
