The Nathan Reflective Tri-Color Vest is a great accessory to use when running at night! What could be more important than a product that enhances your performance? One that keeps you safe. Nathan strongly encourages all athletes to use reflective L.E.D. safety products whenever enjoying outside activity. Nathan reflective and L.E.D. products provide visibility at a minimum of 1,200 feet (roughly a quarter-mile). That's the distance a driver moving at 60 mph needs to detect, react, and maneuver in time to avoid disaster.
