The Speedcraft Air sets new standards: it not only offers clear vision but also ensures long-lasting performance with AC Systems technology. Integrated magnets in the nose bridge attract metal plates that are previously adhered to the nostrils. This enhances nasal breathing and helps athletes achieve peak performance. The nasal dilator is adjusted by turning a small dial in the center of the lens, and the magnetic arms can be opened or closed to control nasal dilation while riding. This revolutionary breathing technique is integrated into the award-winning Speedcraft sunglasses, known for their extensive 360-degree visibility. The large protective lens features a scratch-resistant Hydrolio coating that repels oil and water. The TR90 frame design allows for greater distance between the lens and the face to increase airflow and prevent fogging. Equipped with ultra-grippy rubberized temple arms, the Speedcraft Air rests comfortably on the face and stays in place, no matter how much you sweat.
