Featuring Face Slot Technology the RSi series of irons have a version for all levels of players. The RSi 1 irons feature advanced face design, TaylorMade's thinnest face, deep undercut and inverted cone technology that combine to promote maximum face speed. The RSi 2 irons provide more uniform flexion across the face that protects ball speed and generates more distance on off-center hits toward the heel & toe. And, the RSi TP iron features a Tour-proven shape with its compact head size, minimal offset, and thin top line. Shot-shaping, incredible speed, and maximum forgiveness allows this iron to take your game to the next level.
