The Callaway X-Hot Irons feature the following: Industry leading deep undercut cavity technology was modified to create the longest iron ever. A deeper undercut cavity is designed to provide higher ball speeds over a larger area of the clubface. The Speed Frame Face technology from a driver maximizes ball speeds all across the face for longer, more consistent distance. The feel management badge in the cavity tunes sound while also providing crisp feel.
