With style inspired by the mountain life and the performance to handle its toughest weather, this boot is built to make winter your stomping ground. Equipped with a fully waterproof membrane, we crafted it with a premium, weather-resistant nubuck upper with suede overlays that can handle slush, snow and cold. We perfected a snug, comfortable fit with an innovative Flex Gusset™ in the heel to smoothly enter and exit the boot, no lace adjustment required. The interior liner’s warm, moisture- and odor-managing merino blend topped with soft, piled fleece warms feet without overheating. Offering our toughest traction on slick, snowy or icy surfaces, the lightweight, treaded outsole provides serious grip while the midsole incorporates bio-based materials for a reduced environmental footprint. Molded adjusters on the laces customize fit and suede tabs on the side trap the excess laces.

As caretakers of the mountain life, we recognize our responsibility to support organizations and people who share our vision to drive positive change for people and the planet. We’re proud to partner with some tremendous organizations in their missions to responsibly advance outdoor recreation and protect our wild surroundings.
We are committed to building garments that are durable, timeless and continue to perform season after season. After years of research, testing and product development, in 2024 we completely removed PFAS from all of our newly developed products. We remain committed to growing our Preferred Materials usage, which includes organic cotton, recycled materials and responsibly-sourced down and wool, to 75% by the end of 2025.
Our apparel is built to last. As a part of our efforts to reduce waste and keep more gear in the mountains where it belongs, our home-grown gear renewal program allows previously-used items to be traded in, cleaned, repaired and circulated back into use.
