A Yes they are, but only until the 2017/18 season, when Nike will become the official outfitter of the NBA. Adidas signed a 11 year deal with the NBA in 2006, and the deal will expire for the 2017/18 season. Adidas has already announced they will not be applying/bidding to renew the deal, and that left the door open for Nike; Adidas' primary competitor in North America. In 2006, Adidas replaced Reebok as the official outfitter of the NBA; Adidas purchased Reebok in 2006. Unlike with European sports - like Soccer and Rugby - the NBA sells an outfit deal for the whole league; includes all 30 teams (29 in the US and 1 in Canada). The NBA outfits are made from 100% polyester, the top is a sleeveless vest, and features an NBA and Adidas logo. There is also space on the vest to screen print a name and number. The primary change that Adidas made to NBA vests was to alter the design from a tank top to a sleeveless top; making the vest more suitable for everyday wear. However, this change from tradition was not universally popular. The NBA teams that Adidas currently made an outfit for are: Boston Celtics, Brooklyn Nets, New York Knicks, Philadelphia 76ers, Toronto Raptors, Chicago Bulls, Cleveland Cavaliers, Detroit Pistons, Indiana Pacers, Milwaukee Bucks, Atlanta Hawks, Charlotte Hornets, Miami Heat, Orlando Magic, Washington Wizards, Denver Nuggets, Minnesota Timberwolves, Oklahoma City Thunder, Portland Trail Blazers, Utah Jazz, Golden State Warriors, Los Angeles Clippers, Los Angeles Lakers, Phoenix Suns, Sacramento Kings, Dallas Mavericks, Houston Rockets, Memphis Grizzlies, New Orleans Pelicans, and the San Antonio Spurs.
