The Fenix Headband is specially designed for the nocturnal outdoor enthusiast. It turns your Fenix flashlight into a hands-free headlamp, freeing you to explore, climb, hike and cycle long past sunset. The included 360-degree rotating mounts allow you to attach two flashlights for simultaneous dual-zone illumination at any angle. You can also swap out one flashlight mount for a waterproof battery storage pack. The battery storage pack will safely store your AA or CR123A batteries and has fluorescent o-rings for visibility.
