The HJC RPHA 70 motorcycle helmet features HJC's Plus Integrated Matrix (P.I.M.) shell construction of carbon fibre, aramid and carbon-glass hybrid fibre for an extremely strong superlight helmet. The shape of the shell itself was designed in HJC's wind tunnel to maximise its aerodynamic potential and rear and side spoilers ensure stability at any speed. The RPHA 70 has air channels incorporated into the EPS liner, the vents have a simple slider mechanism allowing you precise control of the airflow and the top vent has been designed to work in both tucked and upright riding positions. For even more comfort, the helmet's MultiCool anti-bacterial lining wicks moisture away and is removeable and washable. The helmet has a detachable anti-fog insert, a height-adjustable internal sun visor, a 'glasses groove' for spectacle wearers and the chin strap has a double D-ring retention. The HJC RPHA 70 Shuky motorcycle helmet has a 5-year HJC warranty against any possible manufacturing fault or material defect. The HJC RPHA 70 series of motorcycle helmets are also available in other colours and graphics. Pinlock included.
