## Long description

BELL 4FORTY AIR MIPS is a mountain bike helmet designed for trail, enduro and all-mountain riding. This size L variant fits head circumferences from 58 to 62 cm and comes in a solid matte black finish. The helmet integrates MIPS rotational impact protection and a ventilation-focused shell design to balance impact management with airflow for longer rides and variable terrain.
Advantages
The helmet combines multi-directional impact protection with a lightweight, well-ventilated shell to reduce rotational forces in a crash while promoting cooling during sustained efforts. The fit system and adjustable visor allow a secure, personalized fit and clear sightlines for different trail conditions. Durable construction and replaceable inner padding support regular use and straightforward maintenance.
Suitable for
 Trail riding where mixed climbs and technical descents are common
 Enduro stages that require both protection and ventilation
 All-mountain riding with extended periods on the bike and varying temperatures
 Daily training rides where comfort and fit stability matter
When it may not be suitable
This size L helmet is not suitable for riders with head circumferences outside the 58–62 cm range; accurate sizing is necessary to ensure proper protection. It is designed for mountain biking and may lack features desired for full-face downhill competition or specialized urban commuting attachments.
Key specifications
 Intended use: mountain bike (trail, enduro, all-mountain)
 Size range: 58–62 cm (L)
 Protection technology: rotational impact mitigation system integrated into the liner
 Shell finish: solid matte black
 Ventilation: multiple intake and exhaust vents for airflow management
 Fit system: adjustable retention for personalized fit and stability
 Padding: removable and washable inner pads
 Visor: adjustable visor for sun and debris protection
How to use
Measure head circumference at the widest part above the ears to confirm the 58–62 cm fit. Position the helmet level on the head, ensuring the front rim sits just above the eyebrows to protect the forehead. Tighten the retention system until the helmet feels secure but comfortable; straps should form a V under each ear and the buckle should fasten snugly under the chin. Adjust the visor angle as needed for visibility. Replace the helmet after any significant impact or when padding or retention components show excessive wear.
What to consider before purchase
 Confirm head circumference to ensure the L size (58–62 cm) is correct
 Check whether rotational impact protection technology matches your safety preferences
 Consider helmet weight and ventilation relative to typical ride length and climate
 Verify compatibility with accessories such as eyewear, communication systems, or cameras
Usage recommendations
Use this helmet for trail and enduro riding where a balance of ventilation and rotational impact protection is required; maintain clean, dry padding and inspect the shell and straps regularly. Replace the helmet after significant impacts or if fit components degrade to maintain protective performance.
