PEARL iZUMi BioViz ® is not just another “hi-vis” thing. Designed from the driver’s perspective, it’s real technology that’s been real-world tested – to grab the attention of humans, not cameras. It’s a complete system that leverages 3M reflectives, true fluorescents and a rider’s movement to be seen faster, and up to five times farther away. By motorists, riders, and our competitors.
