## Summary description

This model in matte titanium charcoal comes in XL (61–65 cm) and features enhanced ventilation, in-mold construction, and adjustable fit for secure comfort.

## Long description

BELL 4FORTY AIR MIPS mountain bike helmet in matte titanium charcoal, size XL (61–65 cm), is designed for trail and enduro riders who need a balance of impact protection, ventilation and fit adjustability. The helmet features MIPS rotational protection, in-mold shell construction for durable weight savings, and an adjustable retention system to secure the helmet across a wide head-size range. Optimized airflow channels and multiple vents help manage heat on longer climbs and technical descents.
Advantages
The 4FORTY AIR MIPS combines a multi-vent layout with targeted internal channels to improve air circulation while maintaining structural integrity through in-mold construction. Integrated MIPS reduces rotational forces during impacts. The adjustable fit system and ample coverage provide a stable, comfortable fit for riders with larger head sizes. The matte titanium charcoal finish offers a neutral, low-glare appearance suitable for varied riding environments.
Suitable for
 Trail riding and enduro where ventilation and impact protection are important
 Riders needing an XL helmet size (61–65 cm)
 Long-distance or multi-hour rides that require breathability and comfort
 Mountain bikers who prefer a helmet with rotational protection technology
When it may not be suitable
This helmet is focused on mountain bike trail and enduro use and may be larger and more vented than necessary for casual urban commuting or road cycling where aerodynamic profile and minimal ventilation are priorities. Riders seeking a full-face helmet for downhill-specific protection should consider a dedicated full-face model instead.
Key specifications
 Size range: XL, fits head circumferences approximately 61–65 cm
 Protection system: MIPS rotational protection integrated
 Construction: In-mold shell bonded to EPS liner for impact management
 Ventilation: Multiple vents with internal airflow channels
 Fit adjustment: Adjustable retention system and straps for secure fit
 Finish and color: Matte titanium charcoal
How to use
Place the helmet level on the head so the front edge sits just above the eyebrows, then fasten the chin strap and adjust it so it is snug but comfortable. Use the rear retention dial or adjustment mechanism to fine-tune lateral and vertical fit until the helmet feels secure without pressure points. Check that the helmet remains stable during head movement and that the MIPS liner sits comfortably; the system is passive and requires no special action during normal use. Replace the helmet after a significant impact or if it shows visible damage.
What to consider before purchase
 Measure head circumference accurately to confirm XL (61–65 cm) is the correct size
 Consider the type of riding (trail/enduro versus road/commute) to match protection and ventilation needs
 Check compatibility with accessories such as goggles, glasses, and helmet-mounted lights
 Plan for helmet replacement after major impacts or after several years of regular use
Usage recommendations
For best performance, pair the helmet with well-fitting eyewear and adjust the ventilation by using available vents to optimize airflow during climbs and descents. Regularly inspect straps, buckles and the shell for wear, and follow manufacturer guidance on service life and replacement after impacts.
