Line Miner Pro boasts the sharpest Oakley optics and widest field of view in one package, giving you the best visual advantage on the mountain. Oakley has achieved this through their new single-layer lens design which reduces distortion, refraction, and reflection, and increases field of view by 20% in comparison to the Line Miner. Partner their industry-leading optics with the fast Switchlock Technology lens changing system, and you’re ready for anything that comes your way. Every Line Miner Pro comes with a 2-lens bundle for easy lens change so you can quickly adapt to changing light conditions, keeping you on the mountain longer.
