Callaway Paradym X Irons combine a Forged 455 Face with the all-new Speed Frame, giving you the best of incredibly long distance technologies and premium forged feel. Each face is uniquely optimized for more speed, higher launch, and increased spin consistency. The all-new Hollow Body design features Speed Frame construction for added stiffness to the body and support for the high-strength Forged 455 Face Cup. This unique construction is the catalyst that stabilizes a thinner face for incredibly fast ball speeds. A forged face and patented Urethane Microspheres deliver the ultra-soft feel and premium sound that discerning players demand. Up to 67g of external and internal tungsten weights are placed precisely to enhance launch conditions and improve speed on mis-hits. This increase in forgiveness is the difference between hitting the green and coming up short. The Paradym X iron features a thicker topline and forgiving sole. A pre-worn leading edge is designed to cut through the turf more efficiently for even more forgiveness.
