Cap Back Design utilizes a revolutionary multi-material construction to support the entire topline from heel to toe. Crafted from a lightweight polymer, it provides stability within the topline and upper perimeter of the face to deliver improved sound and feel while working in conjunction with a reflexive Thru-Slot Speed Pocket™ in a design made to maximize face flexibility, ball speed and distance.

The introduction of Cap Back Design created a full hollow body construction, making way for the new ECHO® Damping System. The fully encapsulated system uses a softer polymer blend and multiple contact points across the face to channel away harsh vibrations creating forged-like feelFast Forgiving Face with Progressive ICT 

The all-new SIM2 Max irons use a fast and forgiving face to give golfers more performance exactly where they need it. An expanded sweet spot has now been intelligently positioned to capture more shots across the club face. Designed to approach the threshold of the legal limit, the new face design is fast, flexible and supremely forgiving. Each face has been uniquely designed to position Inverted Cone Technology (ICT) for optimal forgiveness and minimize the common right miss.

An array of technologies, such as a fluted hosel, 360° undercut and an ultra-thin face, work in unison to deliver an ultra-low CG engineered to produce a high penetrating ball flight.
