The Rain Shadow Pants from Patagonia is light enough to be an afterthought - until the downpour - Patagonia's Rain Shadow Pants give fully seam-sealed waterproof/breathable protection. The Rain Shadow Pants from Patagonia are made from packable and lightweight, H2No 2.5-layer tear-resistant nylon, with a Deluge DWR (durable water repellent) finish and a raised diffusion pattern on the interior that channels moisture away from skin and aids in hassle-free layering. The Rain Shadow Pants from Patagonia features include anatomically contoured knees, flapped zippers running from knee to the elasticized snap hem, and a partially elasticized waistband with drawcord.
