Cap Back Design uses a revolutionary multi-material construction to support the entire line superior from heel to tip. Crafted from a lightweight polymer, it provides stability within the superior line and superior perimeter of the face to deliver enhanced sound and feel while working in tan-together with a thru-Slot Speed Pocket ™ reflective in a design created to maximize face flexibility, the speed and distance of the ball. .

The introduction of Cap Back Design created a completely hollow body construction, giving way to the new ECHO® damping system. The fully encapsulated system uses a softer polymer mixture and multiple points of contact on the face to channel strong vibrations and create a forging feel.

The new SIM2 Max irons use a fast and tolerant face to give golfers more performance exactly where they need it. Now an enlarged sweet spot has been cleverly positioned to capture more shots on the face of the stick. Designed to approach the threshold of the legal limit, the new face design is fast, flexible and highly lenient. Each face has been uniquely designed to position inverted cone (ICT) technology to achieve optimal forgiveness and minimize common right-wing error.

A variety of technologies, such as a ribbed hose, a 360° undercut, and an ultra-thin face, work in unison to deliver an ultra-low CG designed to produce high-penetration ball flight.
