The HJC C91 Nepos brings a clean, modern graphic to a modular helmet built for everyday use. Its advanced polycarbonate composite shell keeps weight down while delivering a secure, comfortable fit shaped through CAD design, making it a great option for commuting or longer rides. The modular chin bar uses a single, glove-friendly lever for quick and easy operation, while the internal sun shield adjusts smoothly to handle changing light conditions. A large top vent works with the advanced channeling ventilation system to move air through deep EPS channels, helping manage heat and maintain airflow throughout the ride. Inside, the SuperCool liner and cheek pads use moisture-wicking, antibacterial fabric to help keep things comfortable. The interior is removable and washable for easy maintenance. With integrated speaker pockets and SMART HJC Bluetooth compatibility, the C91 Nepos keeps you connected when you need it.
