Bell MX-9 MIPS Helmet

The off-road world is a dirty, tough place. Chunks of rock and dirt mean business when launched by roosting tires, and even when its muddy, hitting the ground is always hard. Thats why Bell payed attention to the details on the MX-9 MIPS helmet, 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 Bell MX-9 MIPS packs all these features into one helmet, delivering exceptional value and pro-caliber performance.


  • MIPS Equipped: MIPS stands for Multi-Directional Impact Protecton System, which is a leading slip-plane technology inside the helmet designed to reduce rotational forces that can result from certian impacts. 
  • 3 Shell Sizes: Typical offering requires additional padding to accommodate all head sizes.
  • Anti-Bacterial Liner: Washable liner with quick-drying materials. Inhibits growth of odor causing bacteria and fungi.
  • Shell: Lightweight Polycarbonate/ABS shell construction
  • Certification: DOT
