The off-road world is a dirty, tough place. Chunks of rock and dirt mean business when launched by roosting tires, and even when it's muddy, hitting the ground is always hard. That's why we sweated the details on the MX-9, loading it with a tough polycarbonate shell, Mips energy management system, an adjustable visor, Velocity Flow ventilation, and a removable, washable, anti-microbial 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. 

• MIPS® — Mips (Multi-directional Impact Protection System) is a leading slip-plane technology inside the helmet designed to help reduce rotational forces that can result from certain impacts.
• 3 SHELL SIZES — Typical offering requires additional padding sizes to accommodate all head sizes.
• IONIC+™ PADDING — Quick-drying interior padding helps manage sweat while fighting odor-causing bacteria.
