in sport a jersey is a shirt worn by a member of a team, often with the wearer's name and team number as well. many cycling jerseys of specific colour or pattern represent certain statuses in cycling, such as the "maillot jaune" (yellow jersey) of the leader of the tour de france, or the rainbow jersey. the world cycling union also says a champion must wear the champions jersey in a race, not the team jersey. cycling jerseys are usually made of special synthetic material to help sweat away from the skin. the main garment of an ice hockey uniform, which was traditionally called a sweater, is increasingly known as a hockey jersey. this garment, along with basketball jerseys which are usually sleeveless and baseball jerseys which are usually button up, have become fashion accessories.
