Yellow jersey & Polka dot jersey at a souvenir shop

The Yellow jersey (French: Maillot jaune pronounced [majo ʒoːn]) is the jersey worn by the leader of many multi-stage bicycle races, originally and most notably the Tour de France. It allows the rider who was in the overall lead at the end of the previous day to be easily identified.

The polka dot jersey (French: maillot à pois rouges) is the jersey awarded for the best climber during the mountain stages of the Tour de France cycle race. The "King of the Mountains" wears a white jersey with red dots. ( http://en.wikipedia.org/wiki/Polka_dot_jersey )
