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. • Advanced Fibreglass Composite Shell (AFC): Using HJC's proprietary technology to laminate various specialty materials with rigid fibreglass, the advanced fibreglass composite shell is lightweight yet highly impact-resistant • Advanced Channelling Ventilation System (ACS) : Full front-to-back airflow flushes heat and hu.
