MLB Jerseys

A third jersey or alternate jersey is a sports team's alternate and/or throwback design for the previously established other MLB Jerseys, the home and away outfits. Alternate jerseys are used in all four of the North American major professional sports leagues as well as college sports, semipro leagues, and other sports leagues throughout the world. Though they are termed "third jerseys", the alternate uniform can also include other elements of the uniform or kit, such as pants or socks.
