What is MIPS?

Equipped with pro-level technology but designed with the privateer in mind, the Bell 4Forty Air Mips is the first choice for your next trail helmet.

The 4Forty Air Mips is equipped with pro-level features designed with the privateer in mind. With a sleek new shell and 3-position visor, the benefits aren’t just visibly rad but functionally significant for increased air ventilation, effective sweat management, and better goggle compatibility. Our Float Fit™ system, built-in Sweat Guide™, and Ionic+™ padding ensures all-day comfort, while Integrated Mips® and extended hard-shell coverage help you stay committed in all shred conditions. Upgrades like eyewear ports, a Fidlock® magnetic buckle, and premium straps make the 4Forty Air Mips your go-to for daily trail riding. Availability, certification, color, and pricing may vary per region. If outside of the USA, please check with your authorized local dealer for more information.
