When you're waiting at the gate and the adrenalin is pumping, you probably won't be thinking about the scratch-resistant Lexan® lens that gives you a wide-open view of the track. Or the triple-layer face foam that wicks away your sweat. Or the competition ready design that includes a non-slip silicone treated strap and a mounting interface for Oakley laminated tear-offs, the most advanced tear-off system on the planet (sold separately). But there is one thing you should keep in mind: The winningest rider in history has worn the MX O Frame® in every title chase. And Ricky Carmichael didn't earn his rep by compromising on performance. Flexible O Matter™ frame optimized for comfort, fit and maximized peripheral view. Impact-resistant lens material provides 100% protection against UVA / UVB / UVC and harmful blue light up to 400 nm. Comfortable and secure fit of wide, adjustable elastic strap.
