In a departure from recent iron models, PING’s experts re-engineered the face of the G425 iron by employing a metal-wood-style, variable face thickness (VFT) design. This greatly increases flexing for measurable ball speed gains that launch shots higher and farther with the stopping power to hold greens – a rare result with most of today’s distance-minded irons.

In the process of creating the new face design, they developed a more compact head that sets a new standard for forgiveness for an iron its size. While shorter heel-to-toe than the G410 model, it boasts a 3% higher MOI due to mass savings from the new face geometry that have been re-allocated to the toe and hosel weights, which expands the perimeter weighting and greatly tightens dispersion.

Extensive finite element analysis was used to help develop a multi-material cavity badge that covers more of the face to damp undesirable frequencies and ensure a superb feel and pleasing sound.
