New Mizuno Pro S-4 Iron Set 4-PW Stiff Flex

The Mizuno Pro S-4 has been engineered for accomplished golfers seeking the unmistakable feel of a forged iron with greater forgiveness and confidence throughout the set.

A redesigned curved muscle concentrates mass lower in the head, while progressive offset, a wider sole and deeper center of gravity promote higher launch, increased stability and improved forgiveness without compromising the precision expected from Mizuno Pro.

Forged from a single billet of 1025E Mild Carbon Steel using Mizuno’s patented Grain Flow Forged HD process, the S-4 delivers the exceptional feel, feedback and workability synonymous with Mizuno’s forged heritage.
