Mammut Eiger Nordwand Advanced Down

Product Insights & Style Tips

The Mammut Eiger Nordwand Advanced Down IN Hooded Jacket is built for cold climbs and wind-swept belay ledges, yet it stays light on the body. At its core is 900-fill Mammut Down, delivering lofted warmth in a compact bundle, wrapped in a Pertex Quantum Pro ripstop shell that shrugs off wind, snow, and abrasion. The result is a jacket that feels airy in the hand and serious in the loft, with eco-conscious details like responsibly sourced down, recycled materials, and a PFC-free DWR finish.

On the body, the climbing-specific cut prioritizes movement and layering under a harness. Harness-compatible front pockets, a gusseted hem, articulated patterning, and a low-profile waist adjustment with daisy chain webbing keep the line lean while letting you move through climbs and transitions. The relaxed hip-length fit accommodates midlayers without bulk, making it easy to go from a belay to a chilly street cool-down without missing a beat.

Part of Mammut’s Responsible Collection, this piece signals a shift toward mountain gear that respects the planet while performing at altitude. The Eiger Nordwand ethos—rugged reliability—meets modern sustainability with recycled materials and RDS-certified DRY DOWN, creating a serious outdoor staple that still reads refined when you come off the ridge.
