The pants evolved from the High Sierra Stretch Pants and feature the same movement focused fit and function, but with the added protection of rugged two- layer 20K waterproof / 20K breathable stretch fabric on the seat and knees. The body mapped fabrics offer added insurance if you get caught in a rogue storm or you’re slashing around in sloppy slush. Featuring a tailored fit and super breathable, four-way stretch, abrasion resistant base fabric, the High Sierra Pro Pants are the ultimate touring pants for endurance days in the skintrack covering a wide variety of terrain.
