Born from more than 30-years of composite shaft mastery, the new MMT Taper Iron utilizes a patent pending Metal Mesh Technology (MMT) to redefine the possibilities for feel and performance in a composite iron shaft. A unique metal mesh – made from individually braided strands of 304 Stainless Steel – is integrated into the shaft’s prepreg layers towards the tip. This improves density and stability, while also allowing for thinner overall composite wall construction. Together this yields a finely tuned, highly responsive shaft that still provides the consistent launch and spin control needed for effective iron play. We have these in both taper and parallel. Installation options are available as well. The price of $100 if for a full iron set installation.
