Ready for anything, the highly versatile Kyanite performs as a midlayer or standalone across a range of activities. Delivering warmth, mobility, and moisture management, Polartec Power Stretch Pro allows airflow for breathable comfort and has a durable nylon face for abrasion resistance. The fabric’s brushed interior adds softness, four-way stretch combines with articulated patterning for exceptional freedom of movement, and the streamlined fit layers easily under a shell.
What's been updated: Updated with a more streamlined fit for easier layering, an internal key pocket, and a design that facilitates repair.
