Designed for the most technical alpine expeditions, Mammut's Nordwand Pro HS Pant provides the protection that Swiss mountain guides demand. That starts with GORE-TEX Pro—Gore's most durable waterproof-breathable membrane—but also includes a long list of premium features for mountaineers and backcountry skiers, such as 3/4-length side zippers, water-repellent zippers, Dyneema crampon protection, and the Mammut Gaiter Solution for a perfect seal over our mountaineering or ski boots. These rugged, full-featured pants also feature plenty of stretch and a cut that allows for maximum freedom of movement as we climb, ski, and conquer the mountain.
