Ski tours, fall mornings at camp, chilly days at the crags - the warmest Kyanite’s thermal performance, durability and soft comfort lets it shine as a midlayer or standalone. Polartec Power Stretch Pro has a nylon face for abrasion resistance, and its four-way stretch combines with articulated patterning for exceptional freedom of movement. The unrestricted fit layers easily under a shell, a low-profile ScubaHood adds warmth, and the brushed fleece interior wicks moisture and is really soft.
