Heading for the hills can leave cotton shorts worn and torn, especially if you're bouldering or scrambling around abrasive rocks. The North Face Prolix Shorts offer durability and mobility with a four-way stretch woven Apex Alpha stretch material that's treated with a DWR finish. The tough and fast-drying material is great for active backpackers and climbers who need performance clothing that moves with them down the trail and up to the summit. The Prolix features two front slash pockets and a zippered left cargo pocket that can accommodate a small billfold. The fabric has a Ultraviolet Protection Factor (UPF) of 30+, but don't forget to use sunscreen everywhere else.
