Light, technical and impressively breathable, this alpine wind shell blends efficiency with sustainability for demanding mountain use.
Mammut says:
For exposed routes in dry conditions. This body-mapped windbreaker is part of our athlete-tested Eiger Nordwand range. 20D Pertex® Quantum Air offers abrasion resistance and windchill prevention in the front, back, outer sleeves and hood. A more breathable, stretchier 20D Pertex® Quantum Air at the inner arms and sides cools you down and boosts mobility. With recycled fabric, a PFC-free DWR coating and a patch kit for temporary field repairs, our design approach maximizes performance with fewer resources, creating more environmentally conscious products for the most extreme conditions. Easily packable into its chest pocket, the Eiger Nordwand Advanced WB Hooded Jacket is a go-to shell for when the wind picks up.
Our Verdict
Weighing just 156g (Medium), the Eiger Nordwand Advanced WB Hooded Jacket balances protection and freedom of movement through a well body-mapped layout. The front, hood and outer sleeves use a denser Pertex Quantum Air fabric for reliable wind resistance, while the sides and underarms stretch and vent well during high-output climbs. The athletic cut allows precise movement without excess bulk, and the helmet-compatible hood offers good coverage with easy adjustment.
Pertex Diamond Fuse reinforcement lends reassuring abrasion resistance for such a light piece, and the PFC-free DWR sheds light moisture effectively. Breathability is excellent for a shell in this category, keeping comfort levels high during steep approaches. The chest pocket doubles as a stuff sack, making it easy to stow in a harness or pack lid.
Construction quality feels robust, seams are neat, and the minimal weight does not compromise stability in strong winds. A refined, highly functional layer for exposed routes and fast mountain travel.
