The new HJC F100 is a multi system helmet with an advanced fibreglass composite shell offering both lightweight durability and effective impact protection. Combining the features of a full-face helmet and an open-face helmet, the chin bar can be flipped up to transform the helmet into a more open configuration. The rider can have the protection of a full-face helmet when the chin bar is down, and the convenience of an open-face style helmet when the chin bar is flipped up. • Carbon Shell: premium material utilised in advanced industries, high performance material offering high elasticity, effective impact dispersion and extremely low weight ensuring maximum impact resistance and an ultra-lightweight design • Advanced Channelling Ventilation System (ACS) : Full front-to-back airflow flushes.
