To engineer this Pro version, we took the performance and protection of our MX XS O FRAME and boosted the optics with IRIDIUM lens coating Superheated metal oxides are bonded to the lens at the molecular level to offer balanced light transmission in bright sunlight It cuts glare and hones clarity to a razor-sharp edge while maintaining colour recognition for trail sessions, so you can see the line between the dirt and the greenery These youth-specific designed goggles take advantage of reduced cranial geometry for a comfortable fit on smaller faces The optically pure LEXAN is treated for scratch resistance and mounted in the perfect arc of a circle That translates to clarity at every angle of vision The durable urethane frame stays flexible even in cold weather, and we added an extra layer of face foam to optimize comfort and fit Non-slip silicone keeps the adjustable strap from sliding off your helmet Meets ANSI Z87.1 for high velocity impact Meets EN 1938 for MX goggle requirements inc.: Oakley Microfibre Sock & Cleaning Cloth Delivery: 4-5 Days |
