Tour Influenced Shaping and Design - This is a classic look that the best players want to see, and their extensive input played a huge role in how we designed this set.
Soft Feel - The 1025 mild carbon steel and advanced quadruple net forging creates the soft feel that better players prefer.
Progressive CG for Playability and Precision - Our multi-material design optimizes the Center of Gravity of each club. The longer irons (3-5) have more offset and a tungsten insert to lower CG for higher launch. The shorter irons (6-A) have a higher CG for a controlled, penetrating trajectory.
