Mammut Eiger Nordwand Light Down IN Hooded Jacket – Men's, Eiger Blue

Overview

For fast and light alpine pushes or vertical objectives where every gram matters, the Mammut Eiger Nordwand Light Down IN Hooded Jacket delivers warmth without bulk. It blends responsibly sourced 900‑fill down with recycled synthetic insulation in moisture‑prone zones, delivering loft, compressibility, and dependable warmth as you push through cool air and changing weather. The streamlined silhouette layers neatly under shells or harnesses, while a PFC‑free DWR helps shed light rain and snow when wind bites and visibility drops.

What makes it perform

The Pertex Quantum ripstop shell uses Diamond Fuse technology to boost abrasion resistance, water repellency, and durability without adding weight. A stitch‑through construction keeps warmth evenly distributed, and the regular fit ensures comfortable layering. This jacket finishes with recycled materials and a PFC‑free DWR, striking a balance between performance and responsibility.

Real‑world use cases

Imagine a dawn ascent where every ounce counts and the wind bites at higher elevations. The Eiger Nordwand Light Down IN Hooded Jacket glides on quickly, delivering core warmth as you climb, then packs down neatly in a daypack for easy shedding as the sun warms the day.
