These irons have been in development for over 18 months and are based on research findings that clearly revealed that Natural Golfers want more consistency with their irons. They also said they wanted irons that were easy to hit and more forgiving and accurate – even on miss-hits. They wanted a grip that was soft and tacky, while the shaft or club needed to be lightweight and durable.

The ST110 meets these key findings, plus we have widened the sole and increased the bounce angle to reduce digging to further enhance the playing characteristics of the flatter Natural Golfers swing. With our extensive custom fitting options, we have the best new set of irons ever for the Natural Golfer.

FEATURES

• 10% Lighter in overall swing weight, making it easier to increase swing speed.
• Advanced “Thin-face technology”, only .110 of an inch thick, for perimeter weighting and a cavity size that creates a larger sweet-spot and more forgiveness.
• Square Tracking, heel-to-toe balanced weighting to maintain the square-tracking Natural Golf Swing, where the clubface is squarer to the target line longer than any other swing and club.
  Easy-to-use Swing + Easy-to-hit Iron = Easy-to-Enjoy Golf.
• Lofts and lies engineered for the Natural Golf swing.
• Investment cast from a softer 450-alloy steel in a rich satin finish – promotes a better feel off the clubface.
• Easy-to-hit, progressive cavity-back design with a triangular muscle-back design, keeps the expanded sweet spot in the same area as the loft of the club increases, for exceptional forgiveness.
• A redesigned sole maintains easy-to-hit bounce angle design for Natural Golfers.
• Progressive offset for optimum launch angle in each iron…long irons easier to hit and short irons easier to control.
• Multi-Matched Shaft Technology with a new ST Graphite Shaft with reinforced tip to improve durability and help reduce torque at impact.
• New, lighter, softer, tacky wrap grip completes the optimal total club weight, swing-weight, and balanced club for Natural Golfers.
