Why We like The On Trek Pant

The On Trek Pant allows us to move fast and light, covering huge distances on trail whether we're running, hiking, or backpacking. The four-way stretch material allows us to move freely, leaping across flowing streams, bounding across boulders, and scrambling to the best viewpoint once we've reached the summit. Multiple pockets provide quick-access to our essentials, and the lightweight, packable design fits easily into our overnight backpacking bag.
