The ST/1.3™ is the largest putter grip we make. With a diameter of 1.3-inches and a straight, non-tapered profile, the ST/1.3 maximizes surface area to help golfers reduce their grip pressure and stabilize their hands.
While the smaller ST/1.2™ has a rounded-back design, the ST/1.3 offers golfers a more square shape that helps fill up their hands and aids in consistent hand placement.
TARGETTAC™ TEXTURE
Our new TargetTac™ Texture delivers improved tackiness and feedback. It’s located on the sides and underside of the grip to deliver added texture and improve moisture management.
WHAT BRYSON SAYS
“The ST/1.3 is essentially squeeze-proof, which is what a lot of golfers need with the putter — especially when there’s something on the line.
I can’t imagine anyone wanting a standard-length putter grip larger than this. The ST/1.3 pushes putter grip size to the limit, but it doesn’t go overboard.”
