Eiger Nordwand Advanced Down IN Hooded Jacket - Women's

What Our Gearhead® Experts Are Saying:

"I took the Eiger Nordwand Advanced Down IN Hooded Jacket on a multi-day alpine route and it performed exactly the way a belay jacket needs to when temperatures dropped and the wind found every gap. The Mammut Wall baffle construction genuinely eliminates the cold spots you feel in lesser down jackets, and the harness-compatible pockets and press-button hem seal meant I never had to choose between warmth and function at the belay station."

There is a specific cold that alpine climbers know well. It arrives at the belay, when movement stops and the wind finds every gap in the system, when the difference between adequate insulation and exceptional insulation becomes something felt in the core rather than read on a spec sheet. The Mammut Eiger Nordwand Advanced Down IN Hooded Jacket was built for precisely that moment, tested by athletes in conditions where a thermal layer either holds or it doesn't.

Mammut's Wall baffle construction uses concealed stitch lines to eliminate the cold spots that conventional baffle designs allow through stitched seams. Combined with 900-cuin DRY DOWN fill that maintains loft even when wet and strategically placed down-filled tubes at inside seams, the jacket retains heat with an evenness that serious alpine climbers can stake a route on. Where moisture exposure is highest, recycled G-LOFT ECO EVOX synthetic insulation steps in where down alone would be compromised. The 20D Pertex Quantum Pro shell with Diamond Fuse technology handles wind, rain, and abrasion at a weight that still packs into an included stuff sack small enough to live in a pack pocket for emergencies.

Every detail serves the alpine environment directly. The helmet-compatible 3-way adjustable hood, down-filled draft collar, dual front draft tubes, and press-button hem belay seal function as a unified warmth system rather than individual features. Harness-compatible pockets with a gear loop keep the jacket functional on the wall, and custom cord pullers designed for gloved hands ensure nothing requires dexterity the conditions may not leave available.
