Mammut Eiger Nordwand IN Flex Air Hooded Jacket

The Mammut Eiger Nordwand IN Flex Air Hooded Jacket is built for dedicated alpinists and climbers who demand high-performance kit for fast, technical ascents. Part of Mammut’s athlete-tested Eiger Nordwand collection, this jacket is designed to perform as both a mid-layer and a standalone outer layer depending on conditions. It uses Polartec Alpha Direct Polypropylene insulation, which delivers an outstanding warmth-to-weight ratio while remaining highly breathable and quick-drying to manage moisture during intense efforts. The lightweight yet durable 20D Pertex Quantum Air outer fabric enhances airflow, resists wind, and offers stretch for unrestricted movement across rock and ice. With PFC-free DWR treatment, it provides essential weather resistance while staying environmentally responsible, making it the perfect companion for demanding alpine adventures.

Packed with technical features, the Eiger Nordwand IN Flex Air Hooded Jacket ensures reliable performance when it matters most. The helmet-compatible, single-adjust hood with reinforced peak offers protection without impeding vision, while the articulated, climbing-specific fit guarantees mobility. Practical details include a two-way YKK VISLON front zipper with an easy-repair slider, two chest pockets accessible while wearing a harness, and Polartec Power Stretch Pro inserts on the forearms for added comfort and durability. The jacket conveniently packs into its chest pocket, saving space in your pack, and comes with a repair patch kit for quick fixes in the field. A partially elastic hem, custom cord pullers for gloved use, and Mammut’s focus on longevity make this a versatile, repairable, and expedition-ready insulation piece designed for high-output mountain pursuits.
