Description

The BELL 4FORTY AIR MIPS MTB Helmet is designed for trail rides and off-road adventures thanks to professional-level inspired features. Its Fusion In‑Mold polycarbonate shell ensures a lightweight and durable construction while offering excellent protection.

The Float Fit™ adjustment system combined with a Fidlock® magnetic buckle enables precise and quick adjustment, while the three-position adjustable visor adapts to all lighting conditions.

For comfort, the BELL 4FORTY AIR MIPS MTB Helmet features Ionic+™ antibacterial padding and the Sweat Guide™ system to wick away moisture. No‑Twist Tri‑Glides™ straps and an integrated goggle dock complete this equipment designed for demanding cyclists.
