The Oakley Radar EV XS represent a milestone in the development of cycling glasses for children, and men and women with narrower faces. They are a smaller version of the Oakley Radar EV (Extended View) and, just like their bigger brother, they are the upgraded successor of the legendary Oakley Radars. After many years of research and development working with the world's best athletes, it became apparent that the rider was not looking entirely through the lens, but that their field of vision was partially obscured by the frame. So Oakley set to work developing a larger lens which provides a better, larger field of vision. Surge ports were also added to maintain a cooling air flow. The light-weight but exceptionally durable frame is made from Oakley's unique O-matter material. This, in combination with the HDO and Plutonite lense material, provides the best protection for your eyes. Most importantly, Oakley Radar EV XS cycling glasses are specifically designed for people with smaller faces and/or children. It's time to part with your old Radars and upgrade to these Radar EV XS Prizm's! The legend of the original Oakley Radars lives on in the Oakley Radar EV XS. ''The king is dead, long live the king''.
