Oakley O-Frame MX Goggles When poised at the starting line with anticipation high, it's unlikely that thoughts will drift to the durable Lexan lens that offers expansive track visibility. Nor the triple-layer face foam that effectively removes sweat. Designed for competition, featuring a non-slip silicone strap and a setup for Oakley's advanced tearoff system (available separately), there's one notable point: Oakley MX O Frame Goggles have been the choice of the most successful rider in history throughout every championship pursuit. Ricky Carmichael, whose reputation is built on unwavering performance, made no exceptions in his gear choice. Features: Flexibility even in extreme cold via urethane frame construction Comfortable and secure fit of wide, adjustable elastic strap Minimized reflective glare via interior surface texturing Convenience of 2-pin attachment system for tear-offs Comfort and fit of triple-layer face foam Scratch resistance and optical clarity of Lexan lens material Secure and stable fit via silicon lining on inside of strap Compatible with Attack Mask nose guard Meets Ansi Z87.1 for high velocity impact Meets EN 1938 for MX goggles requirements
