Bought new, never used as it was too big for my wife. 

The i70 is a modern and sleek sport-touring helmet composed of HJC’s advanced polycarbonate material. The full-face shell is noticeably more compact and lighter than its predecessor, the IS-17.  The i70 features an inner, drop-down sun visor with a new, easy-to-use lever. Top vents optimize ventilation into the interior air channels and out through the exterior exhaust vent with an aerodynamic spoiler design.
