The ST-X 230 PLTNM is a high launching, super lightweight draw-biased driver, ideal for slower and moderate swing speeds. It is 30g lighter overall than any possible custom option of the standard ST-X 230.
Mizuno's CORTECH Chamber encases a dense stainless steel weight with elastomeric TPU - taking stress from the clubface and creating an additional energy source. At the same time locating weight closer to the clubface to reduce spin rates. While contributing to a more solid, powerful sensation at impact.
More resilient than commonly used 6-4 Ti, with more complex multi-thickness design - made possible by Mizuno's CORETECH Chamber.
Carbon sole plate now a single piece to allow weight to be pushed to the extremes for overall stability.
With premium Helium Platinum shaft, 3/4" longer than standard and lightweight J112 grip.
Weight located closer to the shaft axis encourages a high, draw biased flight.
4 degrees of adjustability.
