4Forty Air MIPS MTB Helmet

The Bell 4Forty Air MIPS is a well-ventilated trail helmet built for enduro and all-day mountain biking. A redesigned shell improves airflow, while extended hard-shell coverage adds durability and protection for more aggressive terrain.

MIPS Evolve helps reduce rotational forces in certain impacts, and the Float Fit system delivers a secure, adjustable hold. Ionic+ antimicrobial padding and Sweat Guide moisture management keep you comfortable, while a 3-position adjustable visor, integrated eyewear ports and a Fidlock magnetic buckle make it easy to live with on the trail.
