A supreme sport-touring helmet designed for any ride from quick commutes to cross-country cruises. The RPHA 70 ST is exceptionally compact and lightweight as a result of the Premium Integrated Matrix (P.I.M. Plus) shell that provides enhanced shock-resistance with reinforcement materials that include carbon and carbon-glass hybrid fabric. The Advanced Channeling Ventilation System accommodates both upright-style riding for touring and tucked angle riding for sport. This dual-purpose helmet also features an anti-fog visor and internal sunshield that uses a progressive sunshield actuation control for smooth operation. Additional safety features include reflective patches on the rear neck area and an emergency release cheek pad system for safe and quick helmet removal in an emergency situation.
