NAVISOR
Navigation Visor. A device that provides navigation cues in the riders field of view.
The rider has to type in his destination and click Go, never having to look at his phone until he reaches his destination.
Navisor employs intuitive light patterns on the soft LED light guide mounted on the helmet for a seamless navigation experience.
Navisor is water resistant, dust proof and rugged making it a perfect riders navigation assistant.
