The Mammut Eiger Nordwand Advanced WB Hooded Jacket is a specialist windbreaker engineered for technical mountaineering and fast-paced ascents in dry, exposed conditions. As a flagship piece of the athlete-tested Eiger Extreme collection, it utilizes strategic body-mapping to balance weather protection with high-output breathability. The core is constructed from 20D Pertex® Quantum Air with Diamond Fuse technology, providing exceptional abrasion resistance against granite and ice while blocking biting windchill. To prevent overheating during strenuous climbs, Mammut has integrated a lighter, stretchier Pertex® Quantum Air fabric under the arms and along the sides. This recycled, PFC-free DWR-treated shell is the ideal choice for alpinists seeking a lightweight, environmentally conscious layer that thrives where traditional hardshells feel too restrictive and heavy. Precision-engineered for the vertical world, this jacket features a climbing-specific pattern that ensures the hem stays put even during high-reaching moves. The helmet-compatible hood includes a reinforced peak and a 1-way adjustment system for a secure fit in high winds. Functionality is further enhanced by a 2-way YKK® Vislon® front zipper, which allows for easy belay access, and a unique chest button that enables maximum ventilation while keeping the jacket from flapping open. Weighing just 140g, the entire unit stuffs into its own chest pocket, which also features an internal gear loop for harness attachment. Mammut even includes a dedicated repair patch kit, reflecting a "designed for repair" philosophy that ensures this high-performance layer survives the rigors of the North Face.
