| Description |
| Featuring classic Callaway technologies, the Callaway X-20 NG irons have new grooves that conform to the Condition of Competition rules played on Tour in 2010. Its Extreme Notch Weighting provides additional stability and control through a higher Moment of Inertia, while Variable Face Thickness technology creates higher ball speeds over a larger portion of the clubface. The sweet spot is further enlarged by the 180-Degree Undercut Channel for added forgiveness. |
