The TaylorMade PSi Irons meet the demands of better players. They are packed full of TaylorMade’s best technologies and without any compromises. The PSi Irons were designed to be long, consistent, feel good, sound and play good. They feature a progressive design throughout the set; blade lengths, top lines, offset all gradually progress from the 3 Iron right up to the Pitching Wedge, however the progression doesn’t stop there; the long irons have TaylorMade’s Cut-Thru Speed Pockets as well as tungsten weighting to increase the MOI and distance. The short or scoring irons are forged for shot control. The PSi irons also feature a 360° Undercut cavity for a lower CG location for optimal launch trajectories. TaylorMade also gave the PSi irons some other features previously seen in other models; like Face Slots, and the Inverted Cone Technology. In addition, a new feature is their Multi-Material Damping System which gives the PSi irons the feel and sound that better players prefer.
