The design of the Z Force Z-18 iron provides maximum forgiveness and control. The stainless steel cavity design features a shock absorbing port which provides a more solid feel from perimeter weighting while also increasing the moment of inertia. The thinner steel face repositions weight to the toe and heel for added forgiveness and an increased MOI. Optimal iron lofts provide the perfect yardage gapping, combined with a low center of gravity this iron series produces ultimate playability.
