ThruDark

ThruDark brings Special Forces experience to technical clothing with a clean, utilitarian look. Their founders started with a summit suit for high-altitude expeditions, and the team still takes new designs into the mountains, including ski trips in Japan and the Alps. The Ronin ski shells are unlined to stay breathable, leaving warmth to the layers beneath. Polartec Alpha fleece suits that role, releasing heat on the climb and holding it when the pace drops.
