When you're pounding through the rhythm section and the track turns to fuzz, it's because your contact lens has bailed. Oakley 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 and the Oakley standard tear-off system (sold separately). Made of the highest quality optical-grade Lexan®, the lenses are hard coated on the exterior to minimize scratching and anti-fog treated on the interior for unparalleled performance. The strap is patterned with the unique Carbonated graphic and signed with a red Static Icon.
