For those women who live for the beauty of unencumbered, human-powered motion, the Nine Trails Jacket provides support, minimal weight and wind resistance. It's made of tough 1.1-oz. 100% nylon with extremely breathable stretch-woven recycled polyester fabric in the back and underarm panels to vent excess heat. The high-rise, tricot-lined neck, easily pushed-up elastic cuffs, and a drawcord hem seal out chilly weather; a Deluge® DWR (durable water repellent) finish sheds light rain. The jacket now has a center-back reflective zip pocket, and when the temps rise, the shell stashes into its own internal chest pocket. Reflective logos (on the front and back) help keep you visible.
