The ultimate utility iron, 718 T-MB has grown into a full set of uniquely designed irons that deliver effortless distance at every loft in a technical, muscle-back shape. Initially developed as a high launching, player's long iron, the hollow-body, multi-material design of T-MB produces a powerful combination of high launch and forgiveness with a playable trajectory. Advanced hollow-back construction with thin, unsupported L-Face insert allows the face to flex more at impact, increasing launch and speed for more distance. The most high-density tungsten in the Titleist 718 lineup - with an average of 93.9 grams precisely placed in the heel and toe - optimizes launch and spin to produce higher shots that go far and land soft. High-MOI design increases off-center ball speed for forgiveness while delivering stability and tour-validated feel.
