The Pro Combo 2-7 irons are designed with a spring steel face, a forged body and RZN insert to help create more ball speed, higher launching shots, more distance, and improved MOI and forgiveness. The 8-PW are muscle-cavity clubs made from 1025 carbon steel. These one-piece forged clubheads with a shallow cavity are designed to enhance feel and promote a more penetrating trajectory for accuracy and versatility in the scoring zone.

The RZN material, which is a modified version of the material used in Nike's RZN golf balls, dampens vibrations and allows for 45 grams of discretionary weight to be shifted to the toe area, improving feel at impact and increasing stability on miss-hits. Other features of the Vapor Pro Combo irons include progressive blade lengths and sole widths, precision machined X3X grooves, slightly longer, lower profile long irons, and traditionally-shaped short irons.

Introducing the Vapor Iron Family powered by Modern Muscle technology.

Building a better iron starts with listening to the voice of the athlete. At The Oven, Nike's meticulous process of collecting insights and implementing feedback from the world's best athletes has been the driving force behind the development of the Vapor Iron family and Modern Muscle.

The craftsmen at The Oven 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. This face-centered CG is right where it needs to be for optimum performance, precision, stability and ball speed.

Now, Modern Muscle technology will be available in all three members of the Nike Vapor Iron Family - the Vapor Pro, Vapor Pro Combo and Vapor Speed. Because no matter what conventional wisdom might say, there's always better.

• Modern Muscle geometry balances the CG in the center of the face for maximum ball speed, the highest stability and the purest feel.
• Ultra-fast Spring Steel faces amplify ball speed.
• RZN cavity long irons (2, 3, 4, 5, 6, 7) and muscle cavity short irons (8, 9, PW, AW) for the superior combination of stability and shot-shaping workability.
• Weight distributed for high-flying long irons and piercing short irons.
• Progressive sole widths with a beveled leading edge for forgiveness and enhanced versatility.
• Machine milled X3X grooves for enhanced spin control and shot-to-shot consistency.
• Forged 1025 carbon steel body in concert with RZN cavity for refined and consistent feedback.
• Midsize profiles progress from long length, lower profile longer irons, through to classic short irons.
• True Temper DG Pro: Dynamic Gold consistency and precision with progressive ball flight and spin through the set.
• Golf Pride Tour Velvet grip for maximum playability, comfort and confidence.
