EXTOCIS E721 IRONS Consists of high-grade TPU injected into the hollow body pocket creating a new speed-inducing and feel-enhancing VibRCore technology VibRCore performance gel is injected into the hollow body cavity to work with an extremely thick, yet light TPU layer to dampen sound and shock to produce faster ball speed at impact Full-face Diamond Face 2.0 Technology is built with 103 different diamond shapes behind the face that act as mini-trampolines to create faster ball speeds and expand the sweet spot to outer areas of the face 1-piece high-strength steel body with a 360-degree undercut design that lowers the center of gravity to produce a higher launch and increase face flexing, ball speed and overall distance across the entire face Extreme toe weighting elongates the sweet spot for added forgiveness Power-lofted low and deep CG creates distance and lower spin rates, while achieving the same launch characteristics as a standard lofted iron SpeedTested shafts offer the optimal pairing for every flex, determined by robotic testing and validated by player testing Players’ Iron: Smallest, most traditional-looking clubheads; more versatile and less forgiving
