If you consider grueling treks up steep slopes and dense underbrush a mellow day hike, then Norrona made the Men's Bitihorn Dri3 Pant for you. Designed for serious mountain enthusiasts, it features a Dri3 fabric that keeps weight to a minimum while providing premium weather resistance and breathability. The Dri3 fabric is waterproof yet still allows sweat vapors to escape so you stay cool and dry on intense hikes. It's also extremely lightweight and soft for comfort, and a DWR coating adds extra water resistance. When things heat up under the high alpine sun, full length side zippered vents let in cool air quickly. And if you run into deep snow, gaiters with lace hooks prevent it from getting in your boots.
