A third jersey, alternate jersey, third kit or alternate uniform is a jersey or uniform that a sports team may wear in games instead of its home outfit or its away outfit, often when the colors of two competing teams' other uniforms are too similar to distinguish easily.
For home and away jerseys in North America, historical convention has often dictated the colors used by teams in a given league. Teams generally have one jersey which is primarily in a team color, and another jersey which is primarily white (or another light color) and accented with a team color. "White at home" is the convention in baseball (MLB), basketball (NBA, NCAA basketball, and WNBA), minor league professional hockey (AHL and ECHL), and college hockey. "White while away" is the convention in football (NFL, NCAA football), major league professional hockey (NHL), and professional lacrosse (NLL and MLL). Association football (MLS) does not have a "white at home" or a "white while away" convention.
