Highlighted by a design that pays tribute to the historic Pro Staff series, the Pro Staff 97 v13 features a new Braid 45 construction that increases precision by adjusting the angle of the double braided fibers for enhanced feel and stability. Two additional upgrades to this racket include a denser string bed that improves consistency on every shot and a new end cap that is used across Wilson's other performance racket lines for improved comfort and ergonomics.
