Callaway X-22 Tour Iron Set
Performance irons designed for accomplished golfers seeking premium feel and stability.
To improve on the highly successful X-20 Tour Irons, Callaway Golf engineers added new features that allow the X-22 Tour Ironsto play even better and feel even softer. Precision Notch Weighting and a new sleeker hosel combine to raise the moment of inertia (MOI) for better stability and allow the center of gravity (CG) to be moved lower and more in line with the center of the face. This generates ideal trajectories and significantly enhances the level of feel. The head shape has been refined with the thinnest possible topline while still using a 360-Degree Undercut Channel, and the optimized sole width progression provides better turf interaction.
Precision Notch Weighting
Precisely positions more weight to the perimeter of the iron to create a higher MOI for greater forgiveness and stability while maintaining the CG position that produces ideal trajectories and feel.
Tour-Proven Head Shape
Features the thinnest topline possible while still incorporating a 360-Degree Undercut Channel. The blade length is shorter and the CG has been moved lower and in line with the center of the face to provide unparalleled performance with enhanced feel. 
Redesigned Hosel
The sleeker design significantly improves feel and allows the hosel to be more easily adjusted to fit a golfer's custom specifications.
Sole Width Progression
The sole width of each iron has been optimized based on the length and loft to provide better turf interaction through the entire set.
Callaway Golf Core Technologies
VFT Technology maximizes ball speed and perimeter weighting for more distance and forgiveness. 360-Degree Undercut Channel maximizes perimeter weighting by moving the CG lower and farther back in the club head, enlarging the hitting area and stabilizing the club head for more forgiveness.
The legendary performance of the X Series in a new iron with even more forgiveness.
The goal of our X-Series Irons has always been lofty: Set the performance standard for the industry. We've done it again with the X-22 Irons, the best X-Series Irons we've ever made. The perimeter weighting of the X-22s has been maximized for a moment of inertia (MOI) that's 10 percent higher than their predecessors, meaning you get more forgiveness on off-center strikes. The ideal center of gravity position has been preserved, generating optimal ball-flight trajectories. We've also incorporated the Modified Tru-Bore design, dampening vibration for enhanced feel. The tour-inspired head shape has a slightly thinner topline and sole with a large sweet spot for improved aesthetics and forgiveness to boost your confidence.
Precision Notch Weighting
Precisely positions more weight to the perimeter of the iron to create a higher moment of inertia (MOI) for greater forgiveness and stability while maintaining the center of gravity position that produces ideal trajectories and feel.
Tour-Inspired Head Shape
Our engineers took elements designed for Tour players, like a thinner top line and narrower sole, and incorporated them into highly forgiving irons with a higher MOI so they can be played by a wide range of golfers.
Modified Tru-Bore
An advanced version of the original Tru-Bore design, the polycarbonate tip plug at the end of the shaft dampens vibration for enhanced feel and performance.
VFT Technology
VFT Technology maximizes ball speed and perimeter weighting for more distance and forgiveness; S2H2 increases discretionary weight by removing it from the hosel and repositioning it in the perimeter of the clubhead; 360-Degree Undercut Channel maximizes perimeter weighting by moving the CG lower and farther back in the clubhead, enlarging the hitting area and stabilizing the clubhead for more forgiveness.

I purchased these to have something more forgiving since I was playing Ping I3 blades. Since I don't play as often I decided to buy something that would dampen mishit. I have a personal driving range and I found that my swing fault followed me, go figure :) Anyway, my 1st round was a disaster, but it wasn't the clubs. After the disaster I practiced all week with them, along with a major revision in my setup and shot 73 in my second round with them. So, they were redeemed. One thing I've noticed is that the offset is hidden well in the design of the club. I have never cared for offset, but it's almost invisible in this club. They feel really good in my hands and the thicker sole from the Ping's now seem normal.
