Philadelphia 76ers NBA jerseys and apparel, including Allen Iverson jerseys. The Philadelphia 76ers is a team steeped in some serious NBA history. They won their first Championship back in 1955 when they were known as the Syracuse Nationals, then two more when they became the Sixers. The first of those was in 1967 when the team was led by Wilt Chamberlain, and the other in 1983, when Julius Irving and Moses Malone were at the helm. In more recent history, Philly was home to Allen Iverson, who is still considered to have the sickest cross-over ever to grace the NBA.
