Mizuno’s CORTECH Chamber encases a 3 gram stainless steel weight with elastomeric TPU – taking stress from the clubface and creating an additional source of energy.
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 CORTECH 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, ¾ longer than standard and lightweight J112 grip.
Weight located closer to the shaft axis encourages a high, draw biased flight.
4 degrees of adjustability.
4 degrees of loft adjustability to fine-tune look and trajectory.
