After receiving feedback straight from Tour players, Callaway Golf designers decided to refine the X-Forged Irons. The end result is precision clubs that let elite players dissect the course. Forged from soft carbon steel, the clubhead has been redesigned with more bounce and camber and a tighter sole radius. The thin topline, narrow sole and short blade length allow for excellent workability. The Flighted CG Design produces strong trajectories and premium distance control while the new Progressive Dual Notch Weighting allows weight to be precisely positioned for optimized performance throughout the set.
