The Titleist 2010 AP1 Irons are multi-material, dual cavity irons that take the design mission of "Advanced Performance You Can Feel" to new heights. The concept for the original Advanced Performance irons arose as a result of research that indicated serious golfers want performance with great feel, not performance at the expense of feel. The Titleist R&D team?s advanced research group has been conducting extensive sound and vibration analysis aimed at reducing the harsh lower frequency vibration that causes poor feel in irons. This research led to combining several technologies and materials in the back cavity of the new AP irons resulting in a new Tuned Feel System to take feel to a new level. The new Tuned Feel System is a co-molded medallion of soft elastomer and aluminum plate. If want to own this Titleist 2010 AP1 Irons, please feel free to visit our golf irons sale.
