Nike Vapor Pro Irons

Vapor Pro Irons

Modern Muscle. Pure Precision.

Building a better iron starts with listening to the voice of the athlete. When studying Tiger's blades, Nike’s Golf Development team noticed that the wear pattern was directly on the center of the club face, not trending towards the heel where the bulk of the club's weight is carried and where he could achieve a more efficient strike.

”We had this idea, if we moved the CG towards the center of the face that it would have more impact and more mass right behind the golf ball. And it worked. I was able to hit the ball a little bit further, it came off more solid, and the amazing thing is the ball flew better."
– Tiger Woods

Working with Tiger to find a solution, the craftsmen at Nike started drilling holes towards the toe of his irons and filling it with a weighted tungsten plug; an approach that changed the club's CG, offering the purest hit possible and giving birth to what would eventually become Modern Muscle technology. Modern Muscle technology achieves the same adjustment in CG, but does so through geometry instead of a tungsten plug. This updated design method pushes weight to the toe of the club, shifting the center of gravity to the middle of the club face. The face-centered CG is right where it needs to be for optimum performance, precision, stability and ball speed.

Key Technology

• Modern Muscle geometry balances the CG in the center of the face for maximum ball speed, the highest stability and the purest feel.
• Straight leading edges, thin toplines and minimal offset offer the ultimate in alignment and hot-shaping workability.
• Forward weighted for a powerful, piercing trajectory.
• Narrow sole widths for crisp sole/turf interaction and maximum versatility.
• Machine milled X3X grooves for enhanced spin control and shot-to-shot consistency.
• One-piece forged 1025 carbon steel for unfiltered feedback.
• Modernized profiles with longer blade lengths and lower face heights.
