The EXO-R4 helmet continues to set a new standard for EXO's full face street helmets at a very competitive price point. An all new advanced LG polycarbonate shell is more aerodynamic and smaller resulting in an ultra lightweight SNELL-approved helmet. The aero tuned ventilation system uses a large top vent and mouth vents engineered to allow more airflow to the riders head while maintaining low noise levels. The EXO-R4 now features our new Elliptic II face shield with a latching shield locking mechanism located in the lower center of the shield. This makes the face shield more secure and provides a tighter seal against the gasket. The face shield can easily be removed without tools, and the Ever Clear No-Fog coating helps keep your vision clear in cold and damp environmental conditions. The KwikWick II comfort liner is moisture wicking, anti-microbial, quick drying and can be easily removed and is machine washable. . . .
