Mammut Eiger Nordwand IN Flex Air Vest

The Mammut Eiger Nordwand IN Flex Air Vest is designed for alpinists, mountaineers, and climbers who demand lightweight insulation without compromising breathability during intense ascents. Part of Mammut’s elite Eiger Nordwand collection, this vest is athlete-tested to perform in the harshest mountain environments. It features Polartec Alpha Direct Polypropylene insulation, delivering exceptional warmth-to-weight performance while actively managing moisture, ensuring you stay dry even under exertion. The outer shell is crafted from 20D Pertex Quantum Air recycled nylon, chosen for its durability, elasticity, and wind resistance while maintaining excellent airflow. PFC-free DWR treatment adds an eco-conscious water repellent finish, making the vest ideal as a standalone outer layer on aerobic climbs or as a breathable mid-layer in cold alpine conditions.

This vest combines technical precision with repairable durability, ensuring dependable use on demanding expeditions. A climbing-specific articulated fit allows unrestricted movement on rock and ice, while the partially elastic hem improves overall comfort and stability during activity. The 2-way YKK VISLON front zipper not only offers ventilation flexibility but also comes with an easy-repair slider for long-term reliability. Two zippered chest pockets provide secure storage for essentials, with one doubling as a stow pouch for compact packability. The inclusion of a repair patch kit underlines Mammut’s commitment to functional longevity, making on-the-go fixes simple and effective. Designed with alpine practicality in mind, the Mammut Eiger Nordwand IN Flex Air Vest is a lightweight, durable, and highly breathable insulation piece built to thrive in technical mountain environments.
