The Oakley Radar™ Pitch Baseball Sunglasses features all-day comfort, patented optics and a specially engineered coating that provides critically precise vision for you to focus on victory. The Oakley Hydrophobic™ lens coating prevents water from leaving streaks and sheens, which can compromise vision. Whether it's rain or splashing runoff, water can't get a foothold. Skin oils, fingerprints and lotions are easily wiped away without leaving a residue, eliminating the haze that makes ordinary lenses a nightmare to keep clean. High Definition Optics® takes advantage of patented innovations like XYZ Optics® to create unbeatable clarity at all angles of vision. The full spectrum of lens options helps optimize any athletes vision. Fit is very important, and with the interchangeable nosepieces in two different sizes, you can pick the size that works best for you. These sunglasses stay in place using Oakley Unobtanium® to increase grip with perspiration. The aerodynamic design includes surge ports that channel a cooling flow of air, while the O Matter® frame material is engineered to withstand the abuse of athletics. The result is a new milestone in performance technology.
