With the last helmet in the Red Bull branding an era ends for Sebastian which began as a kart driver in 1997. At that time, the only identification beside his racing suit was a helmet in a simple blue-silver Red Bull can design. At his last Grand Prix for Red Bull Racing the circle will be completed, as Sebastian will start with a blue and silver helmet design once again. But just how a Kart developed into a Formula 1 racing car, also the helmet design has evolved tremendously and shines with much effect on the track in the desert state of Abu Dhabi. The small lettering on the helmet needs no further explanation.
