This fits your. Make sure this fits by entering your model number. The P790’s hollow cavity uses SpeedFoam Technology, a new proprietary construction, which serves a dual purpose of generating ball speed as well as optimizing sound and feel. The incorporation of the new wrapped face construction creates a cut-thru Speed Pocket on the sole with extreme flexibility in the lower part of the clubface; it’s this flexibility that creates greater forgiveness and consistency than is typically seen in a distance iron design. For forgiveness and playability, P790 irons feature strategically placed internal metal-injection-molded (MIM) tungsten weighting for precise CG placement and higher moment of inertia (MOI).
