Featuring remarkably ultralightweight construction, world-class softness, and new ball speed technologies, you can achieve enhanced striking distance and better spin simply by swinging naturally. Boosted Ball Speed Our thinnest Titanium Iron Faces ever allow the entire face to flex more extensively. Synchronously, a secondary Rebound Frame flex zone in the sole, supported by the Iron's rigid body, amplifies ball speed to reach unprecedented levels. Progressive Center of Gravity Progressive variable face thickness and a tungsten-nickel weight in the toe optimize speed, stability and launch for every loft. A lower Center of Gravity for Long Irons creates more carry; a higher one for Short Irons emphasizes control. TECHNOLOGY Rebound Frame On the Irons, a thinner face allows the entire face to flex more extensively while grooves etched deep into the interior of the Iron body further enhance flex, especially for shots struck low. Titanium Iron Faces The High Strength Super-TIX-51AF Titanium faceplate is just 2.1mm thick for increased flexibility and maximum ball speed. High-Density Tungsten-Nickel Weight Featured on 5-Iron through 7-Iron A high-density tungsten-nickel weight in the toe greatly increases Moment of Inertia for improved stability at impact. Optimized Center of Gravity by Loft Progressive variable face thickness optimizes speed and launch for each Iron loft. Long Irons are designed for carry, with a lower Center of Gravity to provide enhanced ball speed right where you strike the face. Short Irons emphasize control, with a higher Center of Gravity for better high-low MOI. Loft Specific Groov
