Ultra-thin face for high initial velocity

The unique centroid rib structure has enabled a thinner face, achieving the thinnest face thickness in Yamaha history at just 1.4mm.
This improves the repulsion performance at the impact point of the iron, resulting in overwhelming distance.

Even women can easily achieve high trajectory

The excess weight created by the thinner face has been relocated to the lower rear of the head, resulting in an even lower and deeper center of gravity (compared to the previous model: center of gravity height -1.0mm, center of gravity depth +1.2mm).Even women who are not good at hitting the ball high with irons can now easily aim for the pin with a high trajectory.

Skating Rail Sole that is resistant to duffing
(Skating rail sole)

Yamaha's unique rails gradually contact the ground, reducing impact when the club makes contact with the ground. The rail effect allows the sole to slide even when the club is duffed, greatly reducing mistakes.

The best balance of functionality and sensibility for women too

In addition to the INPRES series' high initial velocity, Yamaha's unique approach has been pursued to make it easier for women to swing.
We've made many small improvements, including a heavier head, a lighter shaft, a slightly thicker grip, and a shorter club length.
