The Icon Airframe Carbon RR Helmet is a top of the line full face helmet design with a hand-crafted fiberglass/carbon fiber/dyneema shell construction. The face-shield is a ‘quick-change-fog-free’ proshield with side plates and provides zero distortion optics. The shield has also been incorporated with a prolock secure shield locking system. There are several removable/replaceable features on the Icon Airframe Carbon RR. The first is a removable, molded breath deflector to help reduce shield fogging. There is also a removable chin curtain, which can be installed to help keep unwanted airflow from coming into the helmet; and finally, there is the removable, HydraDry moisture wicking liner. Oversized intake and exhaust ports are going to guarantee you optimum air circulation.
