Built to buffer the start-stop cycle of alpine climbing in the blowing, blasting, cold and wet, our new Stretch Nano Storm® Jacket blends insulation, breathability and weatherproofness. We paired a light, supple and stretchy 2-layer waterproof/breathable H2No® Performance Standard shell with the revolutionary 60-g FullRange™ insulation of our Nano-Air® and added a highly breathable liner. Together the package is soft and warm, allowing excess heat to move away from the body and keeping the elements out. Each fabric has stretch, complementing the articulated pattern and seamless shoulder design for enhanced ease of movement. Other details include a helmet-compatible, 2-way-adjustable hood, self-fabric hook-and-loop cuff closures and embedded cordlocks at the hem to seal out the elements. The 2-way pit zips and the double chest pockets all use waterproof, PU-coated zippers. Pockets: Two waterproof, PU-coated chest pockets; two welted, high handwarmer pockets with DWR (durable water repellent)-treated zippers and two internal catch-all pockets.
