The E725 Game-Improvement iron design boasts an optimally located CG, maximizing MOI, and aiding extreme stability and resistance to twisting at impact. The extremely low-rearward CG position of the iron-head produces an extremely high MOI and deeper CG position. This super-forgiving design is absolutely loaded with game-changing innovation, including VIBRCOR TPU inside the clubhead, 3D Diamond face technology, and a sleek carbon fiber cap.

MOI+ Design

• The E725 irons extreme low-rearward CG position, which is 10% lower in this design than previous models, produces an extremely high MOI and deeper CG position. The iron design boasts an optimally located CG, maximizing MOI and aiding extreme stability and resistance to twisting at impact.

Vibrcor Technology

• A high-grade TPU strategically injected into deep 360° undercut pocket to create this unique speed-inducing and feel-enhancing internal technology. The E725 irons feature more VIBRCOR in the clubhead to further enhance feel and create more ball speed. VIBRCOR TPU significantly alters the feel of the clubhead, produces faster ball speed, dampens sound and for maximum forgiveness and power off the face. VIBRCOR allows for this sleek, extremely long and forgiving iron head to have the support, sound and feel of a forged iron in an Extreme Game Improvement iron body.

3D Diamond Face

• New 3D Diamond Face is made up of new three-dimensional diamond shapes of variable face thickness behind the face. There are 103 total diamond shapes featured on 3D Diamond Face, comprising of three different 3D thicknesses in an interweaving pattern and features a face thickness reduction on the heel and toe for even greater forgiveness. The mini-trampolines that make-up 3D Diamond Face create faster ball speeds and an expanded sweet spot.

Multi-Material Carbon & TPU Badge

• A new badge in the back of the E725 is made of multi-materials consisting of Carbon Fiber and a high-elastic TPU. Additional stiffness is created by the multi-material badge for shock dampening, sound enhancement and weight savings for an ideal CG positioning with a perfected feel.

360° Undercut Design

• The design is one-piece high-strength steel body with a 360° Undercut Design. It lowers the CG to produce a higher launch and increased face flexing, ball speed and overall distance across the entire face. The multi-material electroform cap now features carbon fiber for added perimeter weighting and improved feel.

Sole Rail Heel/Toe Relief

• Extreme heel and toe relief on the sole is achieved by addition of a heavy substance sole rail. This new sole rial lowers the CG and improves turf interaction for faster speed at impact.
