TThe R66 Goshawk has been designed to suit the road/race rider. Originally named as Prowell's 1st, pure road-racing helmet. The R66 is awesomely light and incredibly strong. The FVS (Frontal Vortex System) on the top of the helmet increases the frontal air intake and induces a strong vortex inside the helmet creating an extremely cool feel when riding at speed. Weight levels have been decreased establishing new benchmarks as well as EPU MQ2IN-MOLD Monobody, LW5D, ISC and a SMART Profile to optimize performance.
