What Our Gearhead(R) Experts Are Saying:"I wore the Eiger Speed SO Hybrid Pant on a fast and light mountaineering day where the weather window was tight, and the pace was unforgiving. The body-mapped construction kept me comfortable through the full effort, and the 3/4 side zippers made it easy to vent without ever breaking stride."Speed objectives live and die by decisions made before you leave the trailhead, and the Eiger Speed SO Hybrid Pant from Mammut is the kind of call that pays off all day long. Designed for trail running and fast-paced mountaineering, this pant is stripped down to exactly what matters and nothing else, moving with you rather than around you from the first step of the approach to the final push for the top. Body-mapped construction pairs different materials where each one performs best, with pre-shaped knees and a gusset crotch keeping movement completely unrestricted at pace. The 3/4-length 2-way side zippers handle ventilation and layering without requiring you to remove your shoes, and laser-cut back vents add passive airflow when the terrain demands everything you have. Stowable attachment hooks and an anti-slip cuff print keep the hem locked over mountaineering boots when the route gets technical.
