The Veil is equipped with only the critical features to keep from weighing you down. We worked with one of the world’s foremost mills for high-end performance materials to develop a fabric that’s ultralight, breathable, and durable. It’s performance focused for the trails and good looking enough, with its matte finish, to wear around town. The front has a YKK full-length zipper, as well as a zippered chest pocket that doubles as a stuff sack for the jacket and is large enough to fit a cell phone when you’re wearing it. When not in use, the three-panel contoured hood can be rolled up and stowed using the Velcro strip at its base. Finally, elastic trim around the cuffs, hem, and hood creates a seal when the breeze picks up.’
