The tennis-racket brand most associated with Roger Federer is Wilson. He used Wilson equipment for virtually his entire professional career, making the Wilson Pro Staff line closely identified with his playing style and public image.
Federer began using a Wilson Pro Staff 6.0 85 as a junior and later moved through several customized Wilson frames. In 2003, the year he won his first Grand Slam title, he used a custom Wilson racket with a 90-square-inch head. That smaller frame reflected the control-oriented equipment of his era.
Wilson later released the Pro Staff RF97 Autograph, a signature model developed with Federer. The racket had a 97-square-inch head and was designed around the stability and precision he preferred, while offering more power than his earlier frames.
The brand is sometimes confused with Federer’s sponsors in clothing and footwear. His racket partnership was with Wilson, while his apparel and shoe arrangements changed over time. The “RF” in the signature racket’s name refers to Federer himself.
