The HJC I90 HOLLEN MC21 flip-up helmet features dual homologation for both full-face and jet helmet use. It boasts an advanced polycarbonate composite shell with a flip-up polycarbonate chin bar, ensuring a lightweight build, superior fit, and exceptional comfort thanks to advanced CAD technology. The helmet is equipped with a sun visor offering a wider field of view to improve peripheral vision, reduce eye strain, and block sunlight effectively. Additionally, the visor is coated to resist fogging and scratches. The interior houses a removable and washable Supercool moisture-wicking liner made from groundbreaking antibacterial, odor-neutral fabric. The cheek pads can be adjusted in varying thicknesses to suit all helmet sizes, and the helmet design is friendly for eyeglass wearers. The RapidFire™ visor replacement system ensures a fast and tool-free visor change. Included in the package is an anti-fog lens. The helmet is prepped to accommodate the optional SMART HJC 10B and 20B Bluetooth communication systems.
