## Summary description

BELL 4Forty Air MIPS is a full-face helmet designed for impact protection with MIPS rotational protection system. It features in-mold construction for integrated shell and liner strength and a matt finish. Intended for cycling and mountain biking where full-face coverage and improved rotational impact mitigation are required.

## Long description

The BELL 4Forty Air MIPS full-face helmet provides comprehensive head coverage and rotational impact mitigation for off-road cycling and mountain biking. Built with in-mold construction, the helmet integrates the outer shell with the energy-absorbing liner to improve structural strength while keeping weight low. A matt finish and a full hard shell deliver durable exterior protection; the integrated MIPS system reduces rotational forces transferred to the head during angled impacts. The design includes extended rear coverage and an adjustable visor to suit trail conditions and rider preference.
Advantages
The 4Forty Air MIPS combines in-mold construction with a full hard shell for a balance of lightweight performance and robust exterior durability. Generous ventilation channels and Float Fit retention provide fit comfort and airflow during sustained rides. The built-in Sweat Guide helps manage moisture for clearer vision and retained comfort. Integrated MIPS rotational protection adds a layer of safety for oblique impacts without significantly increasing bulk.
Suitable for
Trail and enduro mountain biking where full-face protection is preferred
Downhill runs with variable terrain and impacts
Riders seeking added rotational impact mitigation
All-weather trail riding where ventilation and sweat control matter

How to use
Choose the correct helmet size following the manufacturer’s sizing chart and measure head circumference at the brow line. Fasten the retention system and adjust the Float Fit so the helmet sits level on the head and the brow sits just above the eyebrows. Secure the chin strap snugly with no more than two fingers’ width between strap and chin. Adjust the visor and ventilation openings as needed for comfort and visibility. Inspect the helmet before each ride for signs of damage; replace the helmet if it has sustained a significant impact.
Usage recommendations
Use the BELL 4Forty Air MIPS for trail, enduro, and downhill riding where full-face coverage and rotational impact protection are important. Follow local certification guidelines and replace the helmet after significant impacts or according to the manufacturer’s recommended service life. For optimal performance, keep ventilation channels clear and clean the pads regularly.
