A great choice for adventure racing and extra long hikes in changing weather conditions this Oakley Radar Pitch Array includes three interchangeable lenses that allow you to wear one pair of sport eyewear throughout the day. The impact-resistant Plutonite lenses have the excellent vertical coverage but give medium faces a slightly better fit than the larger Range lenses. Oakley's Radar lenses are fully interchangeable so you can switch tints and shapes to suit your needs--or switch to the Radar Range 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 Pitch is one of the most versatile sports eyewear designs you'll find this season.
