Developed in collaboration with Dani Arnold and David Lama, the Mammut Zephir Alpine Harness is made for alpinists who want to travel light and move fast. Its minimalist design keeps weight to a minimum, while the belt's split webbing ensures optimal comfort. The flat design of the waist belt means it can be worn comfortably with a backpack. Stitched daisy chains allow you to individually position ice-screw carabiners, and four large, yet lightweight gear loops handle any extra hardware. All of it adds up to explain why the Zephir Alpine has been used everywhere from remote locales in Patagonia to the classics in Chamonix.
