The Men's Patagonia M10 Storm Pant is a waterproof pant for combating harsh mountain conditions during alpine climbs. The lightweight H2No Performance Standard shell is constructed with 100% recycled nylon ripstop fabric that offers reliable waterproof protection, while the slick jersey backer enhances freedom of movement and allows for smooth layering. Designed with a regular fit and tapered legs, these pants include elasticized cuffs with tie-down loops to help with precise foot placement. A secure, zippered right-thigh pocket provides convenient storage for small essentials.
