Mammut Eiger Nordwand IN Flex Air Vest Men

The Mammut Eiger Nordwand IN Flex Air Vest Men is a lightweight insulated vest for active mountain use and climbing. It pairs breathable materials with fast‑drying insulation and a sport cut that allows unrestricted movement.

Key benefits

• High breathability from 20D Pertex® Quantum Air — reduces overheating during sustained effort.
• Polartec® Alpha® Direct insulation — lightweight, air‑permeable and quick‑drying for consistent warmth.
• PFC‑free DWR treatment repels moisture without fluorinated chemicals.
• Two zip chest pockets and a two‑way front zipper for easy access and secure storage.
• Packs into a pocket and a partially elastic hem improves fit during dynamic movement.

This vest is intended as an active insulating layer for climbing, alpinism and fast mountain approaches. Suitable for spring to autumn use or as a mid‑layer under a shell in colder conditions.
