## Summary description

BELL 4Forty Air MIPS is a full-face protective helmet with in‑mold construction and a matt finish. Designed for head impact protection, it features MIPS technology to reduce rotational forces. Suitable for cycling disciplines requiring full-face coverage, it provides robust protection for commuting, trail and gravity riding where enhanced safety is needed.

## Long description

BELL 4Forty Air MIPS is a full-face helmet with in‑mold construction and a matt finish, engineered to provide head impact protection for off‑road cycling. The helmet integrates MIPS technology designed to reduce rotational forces during angled impacts, extended rear coverage for added protection, and a full hard shell for durability. Its design includes generous ventilation and an adjustable visor to suit varying trail conditions, while the Float Fit system and built‑in Sweat Guide improve fit and comfort for extended use on commutes, trail rides and gravity sessions.
Advantages
The helmet combines in‑mold construction with a full hard shell to balance impact resistance and overall weight. Integrated MIPS reduces rotational acceleration in certain crash scenarios, and extended rear coverage increases protection around the occipital area. Ventilation channels and the Float Fit retention system enhance wearer comfort during long rides, and the matte finish offers a low‑glare appearance. An adjustable visor provides flexibility for different sun and trail conditions.
Suitable for
All‑mountain and trail riding where full‑face protection is preferred
Gravity and enduro disciplines requiring robust impact coverage
Commuting in mixed urban and off‑road environments where extra protection is needed
Riders seeking a ventilated full‑face helmet with rotational protection
Key specifications

Finish: matt surface
Fit system: Float Fit retention for adjustable fit

How to use
Place the BELL 4Forty Air MIPS on the head so the brow rests level and the extended rear covers the back of the skull. Adjust the Float Fit retention to achieve a snug but comfortable hold, then secure the chin strap so it sits flat under the jaw and can be fastened without excessive slack. Position the visor to reduce glare or deflect debris, and ensure ventilation openings are not obstructed by clothing or accessories. Inspect the helmet before each ride for signs of damage and replace it after any significant impact according to manufacturer guidance.
Usage recommendations
Use this helmet for activities that require full‑face coverage and rotational protection. Verify regional certification and sizing with your local authorized dealer, and replace the helmet if it shows visible damage or after a substantial impact. Keep the matte finish clean with mild soap and water; avoid solvents or abrasive cleaners that could degrade the shell or integrated systems.
