The company's new X Hot irons employ a thinner face design
In the X Hot irons, Callaway takes the "Speed Frame Face Technology" it's been using in its drivers and utilized it in irons. That tech is designed to create a better transfer of energy from clubface to golf ball, thereby boosting ball speed and distance performance. These irons also use a Deep Undercut Cavity design to move the center of gravity lower (helping with launch) and move the "hottest" part of the clubface lower, as well. The X Hot irons also incorporate "Feel Management Technology" in the back of the clubhead, for crisper feel and sound. "The X Hot Irons have been meticulously engineered - both in terms of physical characteristics and club configuration--to increase ball speed and promote overall distance optimization," said Alan Hocknell, Callaway's Senior Vice President, research and development. "And in doing so I think we have raised the bar and created the standard in distance for the irons category."
