Callaway Golf has always had the same goal in mind when it comes to X Series® irons set the performance standard for the industry. The new X-22 Irons don't disappoint and are the best X Series irons Callaway Golf has ever created. By maximizing perimeter weighting, these irons boast an MOI thats 10 percent higher than their predecessors. The ideal CG position has been preserved, generating optimal ball-flight trajectories. The Modified Tru-Bore design has been incorporated, dampening vibration for enhanced feel and the tour-inspired head shape has a slightly thinner topline and sole with a large sweet spot for improved aesthetics and forgiveness that will boost any golfers confidence.
