## Long description

The BELL 4FORTY AIR INTEGRATED MIPS — matte white, size S is a mountain bike helmet designed for off-road riding where ventilation, lightweight protection, and a secure fit are important. It combines an airflow-focused shell design with integrated MIPS rotational impact protection and adjustable retention to meet the needs of trail and enduro cyclists as well as daily riders seeking added safety without excessive bulk.
Advantages
The helmet provides integrated MIPS technology to reduce rotational forces in certain impacts, while the airflow-optimized shell and internal channeling improve cooling during sustained climbs or technical descents. Its adjustable fit system and lightweight construction deliver a balance between comfort and stability, and the matte white finish offers a neutral, low-glare appearance suitable for a variety of riding kits.
Suitable for
Trail riding and enduro where ventilation and rotational protection are priorities
Everyday mountain biking and mixed-surface rides
Riders seeking a compact, size S helmet with adjustable retention for a secure fit
When it may not be suitable
This helmet is optimized for mountain biking and may not meet requirements or rider preferences for full-face downhill racing, BMX park tricks, or other disciplines that require extended chin and jaw protection. Riders who need integrated communication systems or specialized mounts should verify compatibility before purchase.
Key specifications
Intended use: mountain bike / trail / enduro
Protective feature: integrated rotational impact protection system
Shell finish: matte white
Size: S (designed for smaller head circumferences)

How to use
Position the helmet level on the head with the front edge just above the eyebrows, then fasten and adjust the chin strap so it sits snugly under the jaw without causing discomfort.

Decide whether integrated rotational protection and ventilation meet your discipline requirements
