The sweeping, continuous shape of the Adidas Zonyk sport glasses creates a very wide and uninterrupted field of vision. At the same time, this form protects athletes from sunlight, wind and impact. The light and simultaneously sturdy SPX frame with integrated Climacool ventilation system is available in two sizes. Comfortable positioning is aided by the Double-Snap Nose Bridge; temples with adjustable Flex Zones increase grip when on the move. The lenses are quickly and easily changed by means of the special Lens Lock system. Reflecting elements on the frame and sweat blocker assure safety.
