Description THE LEADING FULL-FACE DOT/ SNELL APPROVED HELMET FOR UNDER $150 The EXO-R420 helmet continues to set a new standard for Scorpion 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-R420 now features our new Elliptec™ II faceshield with a latching shield locking mechanism located in the lower center of the shield. This makes the faceshield more secure and provides a tighter seal against the gasket. The faceshield can easily be removed without tools, and the EverClear® 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. The EXO-R420 is an updated true high performance helmet at an unbeatable price.
