See crystal clear in all conditions, thanks to the new 5K lens technology and the Quick Lens Exchange System of these state-of-the-art racing goggles. Our 5K lens technology enhances the perceived contrast and color brilliance on the course for an undistorted field of vision. Perfectly integrated with the DOWNFORCE helmet, the face foam can be exchanged to match your individual face form and the wind seal lips keep the wind out for when every millisecond counts.
