## Long description

BELL 4Forty Air MIPS is a full-face helmet engineered for downhill, enduro and aggressive trail riding. The helmet uses in-mold construction combined with a full hard shell and a matte black/white finish to deliver robust exterior protection while keeping overall weight low. Integrated MIPS technology helps reduce rotational forces in certain impacts, and the extended rear coverage offers additional protection for high-speed and technical mountain biking. Ventilation channels and Float Fit retention enhance comfort during long or strenuous rides.
Advantages
The helmet pairs a lightweight in-mold liner with a durable hard shell for balanced impact performance and durability. MIPS rotational protection is built into the helmet to address oblique impacts. Ventilation is optimized with multiple intake and exhaust paths to encourage airflow and heat dissipation. Float Fit retention and an internal Sweat Guide improve fit stability and manage moisture for better comfort on extended descents and hot conditions. The adjustable visor allows for personalized positioning and added glare protection.
Suitable for
Downhill racing and aggressive descents
Enduro events and stage racing
Technical trail riding with high-speed sections
All-mountain riding where full-face coverage is preferred
Key specifications
Construction: in-mold EPS liner bonded to a full hard outer shell
Protection: integrated rotational impact mitigation system (MIPS)
Coverage: extended rear and full-face geometry for increased protection
Fit system: Float Fit retention for adjustable, secure fit
Ventilation: multiple intake and exhaust channels for airflow

How to use
Choose the correct helmet size according to your head circumference and adjust the Float Fit retention until the helmet sits snugly and level on your head. Position the adjustable visor to block glare without obstructing vision. Fasten and tighten the chin strap so it is secure but comfortable; the strap should form a V under each ear. Before each ride inspect the shell, straps and retention for signs of damage or wear. Replace the helmet after any significant impact or if structural damage is detected.
Recommendations for use
Use this helmet for downhill, enduro and aggressive trail applications where full-face coverage and rotational impact mitigation are desired. Ensure regular inspection and proper fit adjustments; store the helmet away from prolonged sun exposure and chemicals to preserve the matte finish and structural integrity.
