"What Our Gearhead® Experts Are Saying:""I wore the Eiger Nordwand Advanced HS Pants on a mixed climbing trip in the Alps—light enough to move fast, but bomber when the weather turned. The tapered leg fit perfectly over my mountaineering boots without extra fabric flapping, and the drop-seat zipper was a lifesaver on long days in a harness. It’s rare to find pants this light that still feel so protective.""Built for alpine missions where every gram matters, the Mammut Eiger Nordwand Advanced HS Pants blend ultralight packability with GORE-TEX Pro durability. Athlete-tested in the harshest conditions, these pants deliver reliable waterproofing, windproofing, and breathability in a minimalist design that still includes the features climbers and mountaineers rely on. The articulated fit and tapered legs keep movement precise and snag-free, while Dyneema®-reinforced cuffs fend off crampon strikes and sharp rock. A high waistband and low-profile waist adjustment disappear under a harness, and the drop-seat design means relief without removing gear mid-route. Side zips manage ventilation during high-output pushes, and an integrated RECCO® reflector boosts safety in alpine terrain. With a repair patch kit included, these pants are engineered not just for performance, but for longevity in remote environments."
