It is almost impossible to see Valentino Rossi without his Monster cap : he wears it in the circuit as well as in daily life. Monster and Valentino have been together for so many years that a line had to be dedicated to the famous green scratch cap that accompanies The Doctor in the GPs (it is also the sponsor of the Yamaha MotoGP) and in the Rally Monza, the unmissable 4 wheel race at the end of the year that Valentino has won several times.
