Rory McIlroy used a prototype of the Vapor Pro Combo from Nike to win the 2014 Open Championship.
The new Modern Muscle geometry provides a shifted centre of gravity, previously located closer to the heel, but now moved toward the centre of the face.
The long irons feature a forged chassis with a thin, high strength, machined face and a lightweight RZN insert to promote faster ball speeds, higher trajectory, and increased stability with pure feel.
The short irons feature a forged construction with a shallow cavity to promote a strong, penetrating trajectory for enhanced shotmaking.
“I tested a prototype version of the Vapor Pro Combo two iron for a few months and worked with Nike to make it better for me,” said McIlroy, after winning the Open Championship.
“They brought me this two iron to try out at the Nike Performance Fitting Center at Archerfield last month and I loved it. It was an instant hit and I immediately put it in the bag at The Scottish Open,” he said.
For the first time, Nike Golf club engineers incorporated proprietary, lightweight RZN material, a modified version of the material found in the core of Nike Golf’s line of RZN golf balls, in the cavity of the Vapor Pro Combo long irons.
RZN technology displaces 45g of material to the perimeter of the clubhead while tuning impact feel.
“The Vapor Pro Combo is one of our most innovative iron constructions to date,” said Nate Radcliffe, Nike Golf’s director of engineering.
“Our precision application of multiple materials throughout this Modern Muscle design has fueled the breakthrough performance characteristics that our athletes such as Rory are reporting back to us,” he said.
“This iron has the clean lines and workability of a blade with the forgiveness of a game-improvement iron,” said Radcliffe.
The Vapor Pro Combo is constructed with progressive technology and geometry throughout the set, a concept first brought to market by Tom Stites with the original Nike Pro Combo in 2002.
“We recognized that athletes had different requirements throughout their set of irons,” said Stites.
“The original Pro Combo was an industry first in the mixed set category and this Vapor Pro Combo represents our most refined version to date,” added Stites.
Precision-machined X3X grooves are used for spin control and shot-to-shot consistency, while progressive blade lengths and sole widths featuring a beveled leading edge are used for forgiveness and enhanced versatility.
Slightly longer, lower-profile long irons and classically-shaped short irons give the Vapor Pro Combo irons a modernized, updated look.
