Modular helmets allow the safety of a full face helmet while providing the option of an open face feel. HJC's CL-Max II is a great entry-level modular helmet for riders of all styles. The polycarbonate shell construction keeps the helmet lightweight and safe, and the ACS scoop ventilation system brings consistent cool air in and flushes the warm air out the back. The antibacterial liner and cheekpads are all fully removable, washable and replaceable. Finally, the bluetooth ready compartment allows for easy installation of the Chatterbox or any other bluetooth system on the market.
