Wilson is a major manufacturer of tennis rackets. The original kevlar Pro Staff model racket, known for its use by Pete Sampras, was heavy (more than 350g strung) and small-headed (85 sq. in.); Roger Federer also used the same racket model. As of 2015, he uses the Pro Staff RF97 Autograph model that is heavy (340 g/12 oz unstrung) and larger (97 sq. in.). Jim Courier and Stefan Edberg also used the Pro Staff Original, Edberg later switching to the Pro Staff Classic in 1991, which was the same racket (85 sq. in. with slightly rounded frame edges) but with different paint work. In late 2009, Wilson unveiled their latest line of rackets, codenamed 20x, which they would later rename BLX. This line directly replaces their previous K-Factor series with all new technologies. Also, many pros use custom-made rackets that perform differently from the mass-produced versions.

Aside from tennis rackets, the Wilson sporting goods company also makes tennis balls (including the official balls of the US Open and starting in 2020, the French Open major championships), shoes, balls, strings, clothes, and racquet bags.
