Great for long treks and adventure races in changing weather conditions this Oakley Radar Path Array includes three interchangeable lenses that allow you to wear one pair of sports eyewear throughout the day. This award-winning design features impact-resistant Plutonite lenses that offer excellent vertical coverage but give medium faces and even some small faces a better fit than the larger Oakley Range and Pitch lenses. Oakley's Radar lenses are fully interchangeable so you can switch tints and shapes to suit your needs--or switch to the Radar Pitch lenses (not included in this array) if you want the additional coverage. Oakley treated their lenses with a permanent hydrophobic lens that repels skin oil rain and sweat to optimize optical performance. The lenses also resist smudges and clean easier than previous eyewear. This award winning design (Outside Magazine's Gear of the Year award for 2007) also has interchangeable Unobtainium nose pieces that you can choose to match your facial contours. From golfing to biking to trail running Oakley's Radar Path is one of the most versatile sports eyewear designs you'll find this season.
