## Long description

BELL 4FORTY AIR — mountain bike helmet in size M (55–59 cm) finished in Matte Dark Green Orange. Engineered for trail and all-mountain riding, this helmet combines a lightweight in-mold shell with targeted ventilation to manage airflow and maintain rider comfort during extended efforts. The mid-size fit covers key impact zones while supporting a low-profile design that works with goggles and most trail eyewear.
Advantages
The construction uses a durable outer shell bonded to energy-absorbing foam to deliver certified impact protection without excessive weight. Large vents and internal channeling promote consistent airflow to help dissipate heat on climbs and during active riding. The helmet’s fit system allows fine adjustment for a secure, centered position and reduces lateral movement on rough terrain. Matte Dark Green Orange finish provides a subdued appearance with visible accent color for on-trail recognition.
Suitable for
Trail riding and all-mountain day trips
Cross-country rides where ventilation and lightweight feel are important
Everyday training on mixed terrain
Riders seeking a medium-size helmet that fits 55–59 cm head circumference
Key specifications
Size: M, fits head circumference 55–59 cm
Shell: lightweight in-mold construction
Ventilation: multiple large vents with internal channeling for airflow
Fit system: adjustable retention for precise fit and stability
Finish: Matte Dark Green Orange
Intended use: trail and all-mountain cycling
How to use
Select the M size to match a 55–59 cm head circumference. Position the helmet level on the head so the front edge sits just above the eyebrows, then tighten the retention system until the helmet is snug but comfortable. Adjust side straps to form a V around each ear and secure the chin buckle, leaving enough room to breathe but preventing excessive movement. Before each ride inspect the shell and straps for damage and ensure vents are clear of debris.
Usage recommendations
Use this helmet for trail and all-mountain cycling where a balance of ventilation, protection and low weight is required. Replace the helmet after any significant impact even if no visible damage is present, and follow manufacturer guidance for cleaning and storage to maintain performance.
