What Our Gearhead(R) Experts Are Saying:"On big alpine routes, I need pants that can handle driving snow and granite scrapes without slowing me down. These have bomber Gore-Tex Pro waterproofing, smartly placed reinforcements, and full articulation for climbing. The side zips are clutch for venting on steep approaches or adjusting over boots."From icy north faces to wind-whipped ridgelines, the Mammut Eiger Nordwand Pro HS Pants give us the freedom and protection to move with confidence. The 3-layer Gore-Tex Pro fabric with an ePE membrane delivers elite waterproofing, windproofing, and breathability, keeping us dry through intense snowstorms while shedding heat on strenuous climbs. Recycled nylon and a PFC-free DWR finish ensure this performance comes with a lighter environmental footprint. A climbing-specific pattern allows for full articulation, while strategically placed top stitching adds tear strength where it matters most. Adjustable suspenders and a high-back waistband keep coverage secure, and dual-side adjustment tabs work seamlessly even with gloves on. The 3/4-length AquaGuard side zippers make venting and boot adjustments easy, giving us a versatile, expedition-ready shell for technical alpine missions.
