Oakley GP-75 Radarlock Sunglasses follow in the styling traditon of the original Oakley Blades. That is to say, styling based purely on high-performance function. Oakley performance features have come a long way since the Blade, though. From Switchlock Lens Technology to High Definition Optics, the Radarlock is packing some of the most innovative technology for until-now-unheard-of optical performance. On top of that, Oakley added GP-75 Limited Edition styling for a truly exclusive look.

  • Switchlock Technology lets you change lenses quickly and easily without stressing or smudging them
  • Two sets of lenses (one for bright light and one for low light) included
  • O-Matter frame is stress-resistant and ultra-lightweight
  • XYZ Optics ensure distortion-free vision for the entire width of the lens
  • Plutonite lens exceeds ANSI 787.1 for impact-resistance and blocks 100% of UVA, UVB, and UVC light
  • Interchangeable icons so you can change the look with your mood
  • Unobtainium hydrophilic nose and temple pads eliminate slipping
  • Multiple Unobtainium nose pad options for a customizable fit
  • Patented three-point fit maintains optical alignment
  • Included retaining strap for when the ride or run gets intense
