Fall hikes, mornings at camp, evenings on hut-to-huts, a midlayer when it's really cold, recovery after a day climbing you'll find all kinds of reasons to wear the Kyanite Pant from Arc'teryx. Warmth, mobility, and comfort come from the Polartec Power Stretch Pro fleece. It allows airflow for breathability and has a soft brushed interior for insulation. The fabric's four-way stretch combines with articulated patterning for exceptional freedom of movement, and an internal pocket stashes your smartphone.
