The Taylormade SLDR iron features an improved Speed Pocket design with ThruSlot Technology which promotes fast speed and high launch across the face of the club. This improved cut through Speed Pocket technology is coupled with an ultra-thin face (1.5mm) and new deep under-cut design promoting consistently higher ball speeds and optimal trajectory in every shot. Each SLDR iron is individually engineered to maximize distance and to tighten the gap between your long irons and metal woods. In addition to the improved Speed Pocket in the mid and long irons, the redesigned cavity and badging provides remarkable feel in the short irons and the tour inspired wedges design have the ATV sole configuration. The combination of distance, performance and forgiveness is what you can expect from the game changing SLDR irons.
