  • The latest evolution of a sunglass that shot to #1 when it was first released, this rebirth of an Oakley classic puts fresh mojo into retro-meets-Revolutionary. Oakley Twenty brings the sure grip of Unobtainium® components to active lifestyles, and it takes clarity and comfort along for the ride. Sleek contours of durable O Matter® frame material are matched with premium optics to turn sunglasses into a performance essential and a statement of style.

    If it feels like your sunglasses are wearing you, you’re not alone. Lots of people find ordinary sunglasses to be a sinister plot, especially with frames that stick out too far at the sides. Oakley Twenty is different because it was engineered with condensed cranial geometry, an innovation that doesn’t simply make things smaller – it carefully hones each dimension so the frame feels like it was made for you. Somebody finally got it right.


    • Optimized peripheral vision and side protection of 8.75 base lens curvature
    • Meets optical requirements based on ANSI Z87.1
    • Meets impact requirements based on ANSI Z80.3
    • UV protection of Plutonite® lens material that filters out 100% of all UV & harmful blue light up to 400 nm


    • Durability and all-day comfort of lightweight, stress-resistant O Matter® frame material
    • Comfortable fit on small to medium faces via condensed cranial geometry
    • Precision and durability of sculpturally integrated hinge mechanisms with dual action CAMS
    • Comfort and Performance of Three-Point Fit that holds lenses in precise optical alignment
    • Patented Unobtainium® earsocks and nosepads ensure a snug, secure fit

  • 3 out of 5 I bought these as a replacement after my others were lost. I choose these because the price was $40 less than other sites. I received the glasses on time and packaged correctly, but the quality was lacking. The lenses do not fit properly in the frames and "squeak" when pressure is applied (for example taking them off and on). Also, the hinges seem weak.
    Barret, we're sorry the glasses don't hold a candle to your original pair. The items we receive come directly to us from the manufacturer, so we can't say for certain if they're being manufactured differently than in the past. We'd be happy to talk with you and see if you may have received a defective pair or are possibly eligible for a manufacturer's warranty. - TacticalGear.com

About Oakley

Oakley collage Since the 1980s, Oakley has been providing U.S. troops with military gear and boots. Best known for its popular eyewear, it has spent millions on developing products for those in the armed forces. This partnership was formed to develop new technologies that improve the safety and performance of soldiers. Over time, Oakley's military line has transformed from a few models to a highly specialized division within the company. At its research facility in California, the company constantly works on new innovations. Some items are not available in retail stores, but luckily a number of military items can be purchased through public outlets.
