The HJC i90 Davan MC4HSF is a versatile helmet with dual homologation for both full-face and jet helmets. It features a highly advanced polycarbonate composite shell with a flip-up polycarbonate chin bar that balances lightweight design, superb fit, and exceptional comfort, thanks to cutting-edge CAD technology. The helmet integrates a sun visor with a broader field of view, enhancing peripheral vision, reducing eye strain, and offering excellent sun blockage. It comes with an anti-fog and scratch-resistant coating. The interior is adorned with a removable, washable, and moisture-wicking Supercool liner made from pioneering antibacterial and odor-neutral fabric. Cheek pads are available in varying thicknesses to fit all helmet sizes. Additionally, the helmet is glasses-friendly. The RapidFire™ Shield Replacement System allows for fast, secure, and tool-less visor changes. An anti-fog insert is included. The helmet is prepped for optional HJC's own SMART HJC 10B and 20B Bluetooth communication systems.
