Mammut Eiger Extreme Collection



Mammut Eiger Extreme Eigerjoch Advanced IN Hooded Jacket

On cold days in the mountains, you should always carry a warm, lightweight, insulating jacket that fits well under your waterproof but is small enough to stash away. The Mammut Eigerjoch Advanced IN Hooded Jacket ticks all those requirements plus a few more!

It has an outstanding warmth-to-weight ratio. The torso is filled with water-repellent 90/10 goose down with 850 fill power, sourced from animal-friendly operations. Under the arms and on the hood, PrimaLoft® Gold Active inserts with 4-way stretch ensure optimal moisture-wicking and freedom of movement - with or without a helmet.

The outer material is the water-repellent and highly abrasion-proof Pertex® Quantum, so you can thrutch up chimneys and swing your backpack around without worrying about your jacket surviving.

The same ground-breaking cut that’s used for the Eiger Extreme Nordwand jacket ensures that the Eigerjoch IN Hooded Jacket sits perfectly, with all the freedom of movement you need for climbing or mountaineering. All that, and it will stow neatly away in the chest pocket.

Please note - sizing is very snug on these tops, as with all the Mammut Eiger Extreme range.
