Mammut Eiger Nordwand Advanced Down IN Hooded Jacket - Men's Eiger Blue, M

What Our Gearhead(R) Experts Are Saying:"This jacket is a game-changer for cold alpine missions. The 900-fill Mammut Down packs incredible warmth into a light, compressible layer that disappears in the pack but shines when the temps drop. I love the articulated cut-it moves naturally when climbing and doesn't ride up under a harness. It's the piece I never head into the mountains without."When we're pushing toward icy summits or standing on a windswept belay ledge, the Mammut Eiger Nordwand Advanced Down IN Hooded Jacket keeps us warm without weighing us down. Designed with high-alpine performance in mind, this piece balances warmth, durability, and freedom of movement, making it a cornerstone of our mountaineering kit. At its core, 900-fill Mammut Down delivers lightweight, compressible insulation with serious loft, wrapped in a Pertex(R) Quantum Pro ripstop shell that sheds wind, snow, and abrasion. The climbing-specific cut includes gusseted legs, articulated patterning, and a low-profile waist adjustment with daisy chain webbing-perfect for layering under a harness. Harness-compatible front pockets, a gusseted hem, and a relaxed fit round out a jacket that's as technical as it is reliable. Responsibly sourced down, recycled materials, and a PFC-free DWR treatment give it both performance and eco-conscious credibility.
