Designed for alpinists looking to do more but take less, the Kaon Jacket combines intelligent zoning and breathable inserts to offer warmth and protection without the weight penalty. Conceived as the next step in insulated layers, the Kaon Jacket employs a combination of high-loft hydrophobic down, quick-drying synthetic fill and insulation-free underarm sections for the ideal balance of warmth, protection and movement. Its intelligent zoning of materials uses 800 fill power European goose down in the body, quick-drying Stratus® insulation in the cuffs, shoulders and hips and Pertex Quantum Air panels under the arms, ensuring that warmth and flexibility are matched by outstanding breathability when your climb gets intense. Built using Atmos® lightweight ripstop nylon, the Kaon Jacket uses a half-hem drawcord and elasticated cuffs for a close fit, alongside a YKK front zip and features a chest pocket for storing essentials. With stitch-through construction and a handy stuff sack for easy packability, you can enjoy the core warmth, active dryness and multi-application versatility of the slim-fit Kaon Jacket, wherever your path leads.
