Built for the highest exertion mountain athletes and objectives, the Nano-Air® Light Hoody offers the same dynamic stretch as the Nano-Air Hoody but with 75% more breathability and two-thirds the insulation. Subtle but stylish, the Untracked Jacket from Patagonia Jackets is a warm, low-bulk snow jacket built for comfort and protection, complete with GORE-TEX® fabric and a DWR (durable water repellent) finish.
