## Summary description

BELL 4Forty Air MIPS is a full-face helmet designed for head protection during cycling and similar activities. It features in-mold construction for a lightweight, integrated shell and liner, MIPS technology to reduce rotational forces, and a matt finish. Suitable for riders seeking full-face coverage, impact protection and improved safety in varied conditions.

## Long description

BELL 4Forty Air MIPS is a full-face helmet engineered for trail and off-road cycling where comprehensive head protection is required. The helmet uses in-mold construction to fuse a lightweight outer shell with the impact-absorbing liner, delivering reduced weight without sacrificing structural integrity. Integrated MIPS technology reduces rotational forces transmitted to the head in certain impacts, while a matt finish and full hard shell give the helmet durable exterior protection and a low-profile look. Design elements include extended rear coverage, an adjustable visor and generous ventilation to balance protection and airflow during demanding rides.
Advantages
The in-mold construction provides a strong yet lightweight shell-to-liner bond that improves impact performance and reduces overall weight. MIPS is integrated to mitigate rotational acceleration in angled impacts. Extended rear coverage and a full hard shell increase protection for more exposed trail scenarios. Float Fit retention and Sweat Guide features improve fit stability and manage perspiration for longer comfort. Multiple vents and an adjustable visor support airflow management and on-trail adaptability.
Suitable for
 Mountain biking and trail riding
 Enduro and aggressive off-road descents
 Riders who require full-face coverage with ventilation
 Commuting on mixed or rough terrain where extra protection is desired

How to use
Select the correct helmet size according to head circumference and follow the Float Fit retention adjustment to achieve a snug, stable fit. Position the helmet level on the head so the front rim sits just above the eyebrows, and fasten the chin strap securely with enough room to allow one or two fingers between strap and chin. Adjust the visor angle as needed for sun protection or improved sightlines. Inspect the helmet before each ride for visible damage, cracks or deformation; replace the helmet after any significant impact or as recommended by the manufacturer.
Usage recommendations
Use the BELL 4Forty Air MIPS for trail, enduro and off-road cycling where full-face coverage and rotational-impact protection are priorities. Keep vents clear of debris, clean perspiration channels regularly, and store the helmet away from direct sunlight and extreme heat to preserve shell materials and fit integrity.
