XR Irons combine several of the most successful features found throughout the Callaway® family, creating the first high-speed, cavity-back, cup-faced irons. Improved Cup 360 technology acts like a spring to increase ball speeds at every impact location, wherever the ball strikes the clubface. You may have heard about the Internal Standing Wave, a critical design feature of these high-speed irons. It's a piece of metal inside the club that, when viewed in cross section, looks similar to a breaking wave. The effect of this piece of metal is to lower the center of gravity and increase the moment of inertia, which makes XR irons more forgiving and easier to get up in the air. An iron built for this much speed requires precise, meticulous craftsmanship. The special construction method Callaway has come up with features a dual-heat treatment that welds the face and the cavity back together, taking iron construction to a whole new level.
