ORDERING GUIDELINES Custom items cannot be returned or exchanged CORTECH CHAMBER 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. Straight Flight Bias CG is positioned further back in the head along the neutral Z axis for a low spin, straight trajectory with launch stability.

Ball speeds most noticeably improved low on the clubface. Forged SAT 2041 Beta Ti Face More resilient than commonly used 6-4 Ti, with more complex multi-thickness design – made possible by Mizuno’s CORTECH Chamber. Unified Sole Composite Carbon sole plate now a single piece to allow weight to be pushed to the extremes for overall stability. HIT Tuned Impact Sound Strategically placed internal sound ribs tune the impact sound to the appropriate frequency and sound pressure.
