A single particle of sand can take down the world s best rider. We engineered this specialized Sand Goggle with closed-cell face foam to keep fine particles from infiltrating the frame & assaulting your vision. It comes with a clear lens for low light & a grey lens for medium to bright light. Oakley s grey lens allows truer color recognition to help you spot trail edges & scattered vegetation that can pose a hazard. made from the highest quality optical-grade Lexan®, the lenses are hard coated on the exterior to minimize scratching & anti-fog treated on the interior for unparalleled performance. The strap is patterned with our unique Carbonated graphic & signed with a red Static Icon. When you re pounding through the rhythm section & the track turns to fuzz, it s because your contact lens has bailed. We designed the MX L Frame™ to fit over your prescription glasses so you can leave the contacts in their case. The comfortably flexible O Matter® frame is fitted with a non-slip silicone treated strap. These goggles are fully compatible with the ATFM half mask & the Oakley standard tearoff system (sold separately).
