This black Arc'teryx Kyanite zip-up hoodie provides warmth, mobility and moisture management using Polartec Power Stretch Pro fabric. Cut for a regular fit, this hoodie has a high neck, zip front, side pockets and a low-profile ScubaHood for added warmth. This Arc'teryx sweatshirt is our one weakness. We really tried to resist adding it to our wardrobe but it seems to be our kryptonite.
