Bell 4Forty Air MIPS MTB Helmet

The 4Forty Air MIPS is equipped with pro-level features yet designed with the privateer in mind.
With a sleek new shell design 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 anti-microbial Ionic+ padding ensures all-day comfort, while integrated MIPS and extended hard-shell coverage helps 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 life.
