A go-to fleece, the highly versatile Kyanite performs as a midlayer or standalone across a range of activities – trail, rock, snow, and camp. Delivering warmth, mobility, and comfort, the Polartec® Power Stretch® Pro fleece allows airflow for breathability and has a durable nylon face for abrasion resistance. And its brushed interior is really soft. The fabric’s four-way stretch combines with articulated patterning for exceptional freedom of movement, and the clean fit layers easily under a shell. What's been updated: Updated with a new fabric made with recycled content.
