The off-road world is a dirty, tough place. Chunks of rock and dirt mean business when launched by tires, and even when it's muddy, hitting the ground is always hard. That's why we focused on the little details with the MX-9, loading it with a tough polycarbonate shell, MIPS energy management system, an adjustable visor, Velocity Flow ventilation, and a removable liner for when the time comes to hose down. The MX-9 MIPS packs all these features into one helmet, delivering exceptional value and pro-caliber performance. DOT approved. Meets the FMVSS 218 Standard.
