Riddell is an American company specializing in sports equipment for American football, baseball, basketball, lacrosse, soccer, softball, track and field, tennis, volleyball, and wrestling. It is headquartered in Rosemont, Illinois.
The company was started by John Tate Riddell. Riddell first invented the removable cleat and then went on to invent the first ever plastic suspension helmet in 1939. In 2008, Dan Arment was appointed president of Riddell. Arment previously worked as executive vice-president and general manager of mass-market business for Easton-Bell Sports, Riddell's parent company, which is owned by private equity firm Fenway Partners. Fenway acquired the company in 2003 from Lincolnshire Management. In 2008, Riddell sued competitor Schutt Sports. Two years later, Schutt filed a lawsuit, also for patent-infringement, against Riddell. Riddell ended up winning, leading to Schutt filing for bankruptcy.
