Built to keep us moving no matter how cold and snowy it gets, the Outdoor Research Arete Modular GORE-TEX Mitten is our go-to for warmth and protection all winter long. The modular design features an outer mitten with a waterproof, breathable GORE-TEX membrane that shields us from piercing winds and wet, heavy snow and a removable liner glove made of soft, comfortable fleece that can be worn on its own in milder conditions. The outer mitt is packed with EnduraLoft synthetic insulation that traps plenty of warmth, even while wet, and the tough nylon and leather outer keeps our hands protected all season long, no matter how many times we wake up before the sun to catch the first chair up the mountain.
