The Nite Ize LED Marker Band is a surprisingly thin, durable polymer strip encased in sturdy nylon fabric, decorated with a reflective pattern for extra visibility. Its fully adjustable elastic band and quick release buckle allow you to wear it snugly and comfortably around your upper arm, and its efficient (100,000 hour) LED which can be set to glow or flash makes you clearly visible by other commuters for up to a mile away. Easily replaceable batteries are included.
