<p>The maximised perimeter weighting on these X-22 Steel Irons 4-SW from Callaway creates a 10% greater MOI than their predecessors, which means that they continue the legendary performance of the X Series in a new iron. The even greater forgiveness means that you will find it much easier to get onto the green. </p><H2>Callaway Club Technology </H2><P>Callaway have used a range of technologies within these X-22 Steel Irons 4-SW to make them a great set of irons to improve your game. Short, Straight, Hollow, Hosel (S2H2) removes discretionary weight from the hosel and repositions it in the more useful position of the perimeter of the clubhead. The 360-Degree Undercut Channel moves the centre of gravity lower and further back in the clubhead, to enlarge the hitting area and stabilise the clubhead for greater forgiveness. </P><H2>Callaway X-22 Steel Irons 4-SW Features </H2><ul><li>S2H2 and 360-Degree Undercut Channel </li><li>Narrower Sole and Thinner Top Line </li><li>Maximise Ball Speed for Enhanced Distance</li><li>Steel Shaft and 12 Month Guarantee</li></ul><H2>Callaway Tour-Inspired Head Shape </H2><P>To ensure that these Callaway X-22 Steel Irons 4-SW can be used by golfers of a range of abilities, the Callaway engineers have incorporated a narrower sole and thinner top line, as used by Tour players, to make these irons more forgiving and improve the MOI. </P><p>A fantastic set of irons to help you improve your game, these Callaway X-22 Steel Irons 4-SW are available now at Onlinegolf.</p>
