Dakine designed the Derail Shorts for riding in the mountains, while wearing pads, by giving them a generous cut around the knees. The shorts are constructed from a four-way stretch. Double-knit nylon and spandex blend provide the strength and mobility playing in the woods demands. And for those in wetter climates, a durable water repellency (DWR) treatment keeps the Derails from being saturated by wet vegetation or light rainfall. For storage, the shorts feature a zippered side pocket and two front hand pockets. Material: Polyester.
