Double the detail, double the attitude. The Oklahoma City Thunder Double Up Flex 110 Snapback brings a bold edge with its high structured 5-panel crown and pre-curved visor for a clean, confident fit. Finished with layered embroidered team logos across the front, visor and side, plus the signature Mitchell & Ness touch, this snapback delivers standout style with everyday versatility. 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.
