The HJC F70 full-face helmet with an integrated sun visor is made of fiberglass. The shell is aerodynamic and tested in the HJC wind tunnel. The visor mechanism is strong and smooth. The visor gives you a wide field of vision and is prepared for a pinlock lens that is supplied in the box, which is an extra plus. There is also an HJ-V9 integrated sun visor that blocks 99% of the UV. On top are 2 ventilation openings that keep the head cool. The cold air is circulated through channels in the EPS and the warm air will escape through 2 ventilation openings at the rear. The inner lining is removable, washable and antibacterial.
