This is not your ordinary outdoor pant. Utilizing a slightly heavier weight, but highly breathable, 4-way stretch, Nylon/Lycra blend, waffle-weave fabric provides for exceptional durability, great range of motion, and next to skin comfort. With thoughtful features including doubled knees and seat, spacious but unobtrusive side zip pockets (they will accommodate your smart phone), built in calf-cinches that keep pant legs rolled up when desired, and exceptional construction make this style an all-mountain favorite. The Washakie is a technical workhorse built for climbing and hiking. With their versatility and comfort you will have them on anytime you're outside.
