When you′re waiting at the gate and the adrenalin is pumping, you probably won′t be thinking about the scratch-resistant LEXANr 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 tearoffs, the most advanced tearoff 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 FRAMEr in every title chase. And Ricky Carmichael didn′t earn his rep by compromising on performance. These goggles are compatible with Attack Mask nose guard.
