Over the course of his 20-year Grand Prix career, Valentino Rossi has slipped his cranium into countless helmets, each with its own design. Most regular-season helmets incorporate the Sun & Moon motif first seen in his freshman GP year. Other helmets are one-off designs created for special events such as his hometown race at Misano, winter testing, Marco Simoncelli tributes, etc. Regardless the occasion, the Aldo Drudi-designed helmets are usually delicious looking lids recognizable by their attractiveness and flamboyancy. Here are my 10 favorites.
