The i90 is a modern and sleek modular helmet composed of HJC’s advanced polycarbonate material. The shell is noticeably more compact and lighter than its predecessor, the IS-MAX2.  The chin bar operates with a single button for an easy one-hand release, even with gloves on. The i90 features an inner, drop-down sunshield with a new, easy-to-use lever. Seven intake vents and two exhaust vents at the rear spoiler allow optimal airflow. SuperCool Interior keeps the rider cool and fresh with moisture-wicking and antibacterial fabric that is removable and washable. The i90 is also Bluetooth compatible, designed for seamless integration with the SENA SMART HJC Bluetooth communication systems (sold separately).
