The gray uniform "celebrates great moments in Celtics history from the famed Parquet Floor" at the historic Boston Garden, which closed in 1995.
The Celtics will debut the uniform for their Nov. 28 game against the Chicago Bulls and will wear it a total of six times during the 2014-15 season.
The uniforms include parquet-inspired piping on the sides and on the shorts and a gold patch showcasing the Larry O’Brien championship trophy.
"We are proud to partner with adidas on unveiling the Parquet Pride collection which honors significant moments in Celtics history and the iconic Parquet Floor," said team president Rich Gotham. "Incorporating our franchise’s storied tradition into our alternate home uniform provides a contemporary new look our players and fans will enjoy, while embracing the history that makes the Celtics brand unique."
Boston will also release a "Parquet Pride" merchandise collection, including T-shirts, hats and other team gear.
