HJC RPHA-11 - Eridano
The HJC RPHA 11 Eridano is a top-of-the-range sports helmet, specially designed and wind-tunnel tested for the highest aerodynamic performance on the race track.
The shell of the RPHA 11 is structured from HJC's signature Premium Integrated Matrix composition (PIM Plus) consisting fo aramid, fibreglass and carbon-fibre for incredible shock-resistance and a lightweight feel on your head, with rear integrated spoiler for reduced buffetting and cutting through the air.
Speaking of air, ventilation at the chin and forehead work to provide fresh air to your face, with outlets on the back to exhaust warm air. The shell's advanced channelling ventilation system means that the air supply is evenly distributed, with a moisture-wicking multi-cool lining for keeping you comfortable throughout.
The helmet's eye port is wider to give better peripheral vision, and an emergency cheek pad system allows you to quickly remove your helmet in the event of an accident. A RapidFire shield replacement system allows for quick removal and installation, and an anti-fog lens included as standard.
