Unlike traditional forged irons, XTD is a multi-piece forging that boasts the category's first-ever Cut-Thru Slot technology. A floating face and hollow design delivers a consistently faster face, adding forgiveness throughout. Tungsten weights in the sole optimize CG location. Better players who prefer a thin topline design and the feel of a forged iron, will appreciate the easy to hit playability of the XTD Forged Irons. The full eight-piece set includes a 3- and 4- DHy, currently the top hybrid model on the PGA Tour. It gives the extra distance and forgiveness of a hybrid with the shot-shaping control of a long iron. A unique bulge-and-roll face technology improves shot dispersion. The most advanced forging ever! Forging is 80+ years old and hasn't really changed – until now! Hollow Forged Design allows for the irons to match the face hotness of the hybrids. Only Cut-Thru slot in golf and it's in a forging, creating a consistently faster face. Includes two DHy hybrids, currently the #1 model on the PGA Tour.
