One of the GOATs
The Wilson Pro Staff line is one of the most iconic and storied racquet series in tennis history, known for its precision, feel, and classic control-oriented performance. Used by legends like Pete Sampras, Roger Federer, and Stefan Edberg, the Pro Staff features a thin beam, head-light balance, and braided graphite construction, making it a favorite among advanced players who prioritise touch and accuracy over power.
Over the years, Wilson has refined the Pro Staff while staying true to its heritage. Recent models, such as the Pro Staff v14, incorporate FortyFive° carbon technology for improved stability and pocketing while maintaining the classic signature crisp and connected feel.
