The F70 is an entirely new helmet style from HJC. The Advanced Fiberglass Composite shell uses HJC's Advanced Channeling Ventalation System to provide 25% improved airflow over their previous fiberglass shell line. 4 intake vents, including 2 chin vents that allow optimal inflow in both upright and tucked riding positions, and 5 exhaust help to maximize airflow. The included breath deflector is oversized to fill the gap below the integrated internal sun shield which runs on a cable system for smoother operation versus the spring loaded system HJC used in earlier models and moves the mechanism to the chin bar for easier operation while you ride, all while reducing the overall weight of the helmet. The shell is constructed to house the all new HJC Smart communication systems powered by Sena, which are sold separately. The eye port is wider and gives the helmet an aggressive overall look. The Stone Grey finish features a slightly rough texture for an extremely unique helmet look. This color is in high demand and we do not expect our stock level to last into riding season.
