SIM Max Irons Don't Just Want Better Shots, Expect Them Cap Back Design The all-new multi-material Cap Back Design utilizes high-strength stainless steel and ultralight weight polymers. Designed to maximize distance, forgiveness and feel with an extremely low CG. Fast Forgiving Face The all-new SIM2 Max irons use a fast and forgiving face to give golfers more performance exactly where they need it. Designed to approach the threshold of the legal limit, the new face design is fast, flexible, and supremely forgiving. New ECHO Damping System The new ECHO Damping System uses a softer polymer blend and multiple contact points across the face to channel away harsh vibrations creating forged iron like feel. Thru-Slot Speed Pocket Patented TaylorMade technology engineered to maximize face flexibility for increased ball speed and forgiveness for mishits low on the face. Progressive Inverted Cone Technology Each face has been uniquely designed to position the Inverted Cone Technology (ICT) on each iron face to optimize forgiveness and minimize side spin to counteract the common right miss.
