The LED Sport Belt is streamlined and lightweight, making it the perfect bulk-free, all-weather, all-season way to be visible when you're out in the dark. Made of durable, weather-resistant nylon, it's flexible and comfortable to wear. The LED is simple to activate-press once for steady glow and twice for flash mode. Its webbed reflective pattern provides secondary passive visibility for added safety, and its 2" width allows you to easily attach most conventionally-sized water bottles and energy gels. The on/off switch is lockable and the bright red LED is powered by three AAA alkaline batteries (included, and easily replaced) that provide 200 Hours of illumination.
