Technology in Detail
Half-Moon Mallet Head Design
The Grant Park features a distinctive semi-circular half-moon mallet head shape that sits between a compact mallet and a full-size mallet in terms of head volume. This design distributes weight around the perimeter of the head, raising the moment of inertia (MOI) and providing meaningful forgiveness when the ball is struck off-center. The clean, uncluttered silhouette at address promotes confidence and a consistent setup routine, while the moderate toe hang makes it particularly well-suited to golfers with some arc in their putting stroke. The result is a putter that looks refined, performs predictably, and suits a wide range of playing styles.
Double-Milled Face
Wilson's double-milled face technology is the performance centerpiece of the Grant Park. The face is machined in two precise stages, creating a micro-textured surface that grips the ball at impact for a smooth, end-over-end roll from the very first moment of contact. This two-stage milling process ensures a consistent feel, roll, and perfect distance control regardless of where on the face the ball is struck — whether in the sweet spot or towards the toe or heel. For golfers who struggle with inconsistent distance on putts, the double-milled face delivers the repeatability needed for confident short-game performance.
Focus Activation Parallel Alignment Lines
Alignment is one of the most critical — and most overlooked — elements of a repeatable putting stroke, and the Grant Park addresses it with a sophisticated triple-line system called Focus Activation Parallel Alignment Lines. A single, prominent central line runs from the back of the head toward the face to help you square the putter to your target line, while two thinner support lines flank it on either side to reinforce and confirm your aim. Together, these three lines work as a visual anchor, sharpening your focus and allowing you to commit fully to each putt with confidence. The system works in combination with the anti-glare finish to ensure the lines remain crisp and easy to read in all lighting conditions on the course.
Two-Tone PVD Anti-Glare Finish
The Wilson Infinite Grant Park is finished in a premium two-tone PVD (Physical Vapour Deposition) anti-glare coating that dramatically reduces unwanted light reflection from the top of the putter head. Glare can be a significant distraction at address, especially on bright, sunny days, pulling your attention away from the ball and disrupting your focus. By eliminating this distraction, the PVD finish allows you to concentrate entirely on the ball and your intended line throughout your stroke. The dark, matte aesthetic also accentuates the alignment sight lines, making them appear sharper and more defined against the head's surface. The finish is durable, resistant to wear, and gives the Grant Park a sophisticated, tour-quality appearance.
Midsize Multi-Textured No-Taper Grip
A great putting grip is the connection point between the golfer and the putter, and the Wilson Infinite Grant Park ships with a specially designed midsize multi-textured, no-taper grip that is engineered to promote a more consistent putting stroke. The no-taper profile means the grip maintains a uniform diameter from top to bottom, encouraging your hands to remain passive and working together throughout the stroke. The multi-textured surface provides tactile feedback and prevents the grip from rotating in your hands during the stroke, while the midsize dimensions help reduce tension in the hands and wrists for a smoother, more fluid motion. This grip is a key reason why the Grant Park promotes such a consistent, pendulum-like putting action.
