Product information

Description

The BELL 4FORTY AIR MIPS mountain bike helmet in matte black camo, size S (52–56 cm), is a trail-focused protective helmet that combines in-mold construction with MIPS rotational impact protection. Designed for trail and all-mountain riding, it offers a balance of ventilation, coverage and fit control to suit riders who prioritize safety and comfort on varied off-road terrain.

Advantages

This helmet integrates MIPS technology to reduce rotational forces during certain impacts while maintaining a lightweight in-mold shell for impact energy management. Multiple ventilation channels promote airflow to help regulate temperature on sustained climbs and technical sections. An adjustable retention system and padded interior provide a secure, customizable fit in the S size range (52–56 cm). The matte black camo finish gives a low-profile visual appearance without affecting performance.

Suitable for

  • Trail riding and singletrack where balanced protection and ventilation are required
  • All-mountain and enduro-style riding with variable terrain
  • Riders seeking enhanced rotational impact protection via MIPS
  • Cyclists who need a compact helmet that fits a 52–56 cm head circumference

When it may not be suitable

The BELL 4FORTY AIR MIPS is optimized for mountain biking and may not be the best choice for road racing where aerodynamic profiles and very low weight are prioritized. Riders requiring full-face or downhill-specific helmets with extended chin protection should consider dedicated downhill models instead.

Key specifications

  • Fit range: designed for head circumferences of approximately 52–56 cm
  • Protection: rotational impact mitigation technology integrated into the helmet
  • Construction: in-mold shell bonded to energy-absorbing liner for impact performance
  • Ventilation: multiple front-to-back channels for airflow management
  • Retention: adjustable fit system with padded interior for comfort and stability
  • Finish: matte black camouflage coloring
  • Intended use: trail and all-mountain mountain biking

How to use

Position the helmet level on the head so the front rim sits just above the eyebrows. Adjust the retention system until the helmet feels snug but comfortable, and fasten the chin strap so it forms a V below each ear with the buckle centered under the chin. Check that the helmet does not rock excessively when you shake your head and re-tighten the retention if needed. Replace the helmet after significant impact or if the shell or liner show visible damage.

What to consider before purchase

  • Measure head circumference to confirm the 52–56 cm size range is appropriate
  • Decide whether MIPS rotational protection and trail-oriented coverage meet your riding needs
  • Check compatibility with goggles or eyewear you plan to use
  • Inspect ventilation and weight preferences for long rides or hot conditions

Usage recommendations

Use this helmet primarily for trail and all-mountain riding. Regularly inspect straps, buckles and the interior liner for wear, clean with mild soap and water, and store out of direct sunlight to preserve materials and fit performance.
