they are a little smaller then expected takes away your peripheral vision
Oakley's MX ENDURO is a face-hugging shield with enough downward visibility to let you choose the best line on track or terrain. The vented dual lens design is enhanced with F-2 Series anti-fog treatment and the clarity of optically pure LEXAN®. Triple-layer face foam wicks away sweat while the silicone treated strap refuses to slip off your helmet. Compatible with ATFM half masks, these goggles integrate perfectly with the Oakley laminated tearoff system (sold separately), so coming through the pack won't leave you dirt blind.
