The Mizuno MP-69 irons' new 4D muscle pad
The Mizuno MP-69 irons are designed with the same playing profile and offset as its predecessor, and the sole design evolved over time from Mizuno's favourite custom tour grinds, features an additional bevel to the trailing edge to allow a cleaner exit from the turf. Besides, MP-69 features a slightly thicker muscle in the back of the head that provide a penetrating and workable ball flight for complete shot control through the set and adds an element of forgiveness.
