LEVEN IRON SET FAST, FORGIVING, AND EASY TO SWING If you swing at or below 90mph, added ball speed can transform how you play golf. With a wholly redesigned cup face structure and profoundly lightweight shaft, XXIO Eleven does this in spades. A remarkable sole design is how we’ve added forgiveness, improving MOI and raising your launch angle for maximum distance. XXIO Eleven also uses our Weight Plus system to actively modify your golf swing for noticeably improved consistency, ball striking, speed and control. MULTI-MATERIAL & DOUBLE UNDERCUT CAVITY A hot forged titanium faceplate, integrated tungsten sole weight, and complex 4-piece construction make XXIO Eleven our most ambitious iron project to date. But we didn’t stop there: our new Double Undercut Cavity is a revolution in cavity back iron design. Two slots cut into the iron body just behind the face dramatically increase flexibility while maintaining strength. It’s a remarkably fast yet resilient design for explosive ball speed that boosts distance on every iron shot. WEIGHT PLUS XXIO Eleven features our most extreme Weight Plus system with our heaviest grip weights in each club. It provides the most powerful swing-improvement characteristics, drastically enhancing your top-of-swing consistency and downswing power.
