The forged Staff Model ZM Wedges feature Wilson's ZM groove pattern and Garnet Face Blasting technique. This powerful combination of a more frictional surface and deeper grooves extends the time the ball is in contact with the face at impact, resulting in higher and more consistent spin rates, even in wet conditions and poor lies. Wilson's staff professionals were instrumental in this tour-level wedge's design from inception to completion. As such, new low-bounce offerings with straighter leading edges and raised centers of gravity were introduced to meet the needs of skilled players. These options allow for controlled, flighted trajectories and the versatility to execute even the most exacting greenside shots. The stock shaft is True Temper's Dynamic Gold Spinner. Engineered with a more active tip section, this Tour Issue shaft further elevates spin rates while maintaining accuracy and tight dispersion.
