Like all NFL franchises, the Packers utilize a third uniform -- usually a throwback set -- that they wear once a season. This comes in addition to the “color rush” uniforms that the league mandates that teams wear during Thursday Night Football. The Packers’ current third uniforms are recreations of the ones they wore from 1937 to ‘48, a navy-and-gold getup that uses the team’s standard helmet without decals. The uniforms celebrate an era that saw Curly Lambeau win his final two championships with the Packers.
Teams can only change their alternate uniforms after five years, and Green Bay introduced their current set before the 2015 season. The Packers can introduce a new set of third uniforms as early as the 2020 season.
