With Sphaera™ Slash, you feel empowered to push all limits. Sphaera Slash is the culmination of years of research conducted alongside athletes. They are designed with an alternative "slashed" lens shape to limit contact with the cheeks, and optimize athletic performance with a wide field of vision and a lightweight O Matter™ frame. Ventilation on the front of the frame improves airflow. Unobtainium® nosepads and molded temples ensure non-slip grip for easy wear with a cap and helmet. You'll discern every detail thanks to Prizm™ lens technology, enjoying enhanced colors and contrasts wherever you go.
