The Icon Mainframe helmet was designed with fit, function, and the rider's safety in mind. The Mainframe helmet features a venturi super-vent system for the ultimate in airflow. Athree position forehead switch acts as an additional ram-air vent to significantly increase the overall cooling of the helmet. The shell is constructed of a Dyneema/fiberglass composite and is lined with a dual-density styrene liner for incredible strength without undue weight. Also incorporated into the design are removable/washable cheek pads, a removable anti-fog breath deflector, and the industry's easier no-tool quick change shield.
