Bell - Overdrive
TheOverbrow Ventilation™ regulates temperature by drawing cool air into the intake ports and circulating it through a matrix of air channels pushing out warm air through the exhaust ports.
Fusion In-Mold Polycarbonate Shell is a process pioneered by Bell that bonds the helmet's outer shell to the EPS foam liner to create a sturdier helmet.
TheTwin Axis Gear™ (TAG) fit system adjusts to the head on two axes-circumferentially as standard fit systems do, but also horizontally to better accommodate differences in the up/down position of the occipital lobe.
Please measure your head size to get the right helmet size.
