The highly versatile Kyanite fleece can be used as a midlayer or as a standalone garment for a variety of activities—on the trail, in the rocks, in the snow, and at camp. Providing warmth, mobility, and comfort, the Polartec® Power Stretch® Pro fleece allows air to pass through for enhanced breathability and has a durable nylon face for abrasion resistance. The brushed interior is very soft. The fabric's four-way stretch combines with articulated patterns for exceptional freedom of movement, and the streamlined fit layers easily under a shell.
