Frame Features

  • Unobtanium- Oakley's proprietary grip technology is embedded in the temples and nose pads. The more you sweat, the stickier and tackier it gets! This keeps the Flak 2.0 XL optically aligned and extremely comfortable.
  • Three-Point Fit System- Pressure is evenly distributed on your nose bridge and behind your ears. Increased comfort gets you through that extra mile or overtime play.
  • O-Matter™ - Lightweight and durable frame construction to meet any of you sport demands. These sunglasses are made to take a lick and keep on ticking.
  • Semi-Rimless Design- Cutting out the bottom of the frame creates a better downward view. Focus easier on fielding ground balls and upcoming terrain.
