Blueprint S has been developed through meticulous testing with top Tour pros to deliver a players iron made for low-scoring performance. A split-set construction allows PING engineers to insert a forged pocket in the cavity of the 3-5 irons, increasing MOI while perfecting the CG placement to give players optimal distance and control. The 6-PW are designed specifically for workability to attack greens confidently. The compact shape, built with 8620 Carbon Steel, features a cavity back design and thin topline with a Hydropearl 2.0 chrome finish that inspires even the best players.
