Make noise in the Oklahoma City Thunder Overprint Boxy Tee, built in a relaxed boxy fit with a heavy enzyme wash for that perfectly worn-in feel. Water-based screen printed custom graphics deliver bold, all-over impact, while the embroidered Mitchell & Ness logo on the right sleeve adds a premium finish. It’s a standout everyday piece with serious edge. The Oklahoma City Thunder was originally established as the Seattle SuperSonics, an expansion team that joined the NBA for the 1967-1968 season. When the Seattle SuperSonics relocated to Oklahoma City after the 2007-2008 season, fans voted on potential nicknames and Thunder was the winning pick. The team set sales records for the first day after the nickname was revealed.
