Speedcraft AIR features the patented AC Systems breathing technology, and comes with magnetic nose stickers to secure and properly operate the system. The nasal dilator is adjusted by rotating a small dial in the center of the lens, and the magnetic arms can be opened or closed to control nasal dilation throughout a ride. This revolutionary breathing technology is incorporated into the award-winning Speedcraft sunglass recognized for its expansive 360 degree visibility. The large shield lens utilizes a scratch resistant HYDROILO coating which repels oil and water. TR90 frame design allows for enhanced space between lens and face to increase airflow and prevent fogging. Finished with ultra-grip rubber coasted temple arms, the Speedcraft AIR rests on the face comfortably, and stays in place no matter how much you sweat.
