MAINFRAME FACE

Using a multi-step AI computing process, we simulated thousands of the most common strikes across the club face, emphasized the impact locations, and evaluated the performance characteristics.

Then, based on our findings, we created a variable thickness face design that enlarged and reshaped the sweet spot for boosted ball speeds across the entire striking area. Inside the clubhead, AI helped us figure out the best location for placement of unique weight pads for maximum forgiveness.

FULL-FACE GROOVES

For the first time ever in an Iron, HALO XL features full-face grooves, so you can step up, swing, and send it with serious spin on every shot. This hosel-to-toe groove configuration performs no matter where you strike the ball. Plus, HALO XL Full-Face features a striking area that's up to 20 percent larger than last generation.

ALIGNMENT LINES

HALO XL Full-Face features a new, two-groove alignment system for reliable, consistent aim. Two thicker, white grooves on the bottom of the face help you keep the face square at address, centered behind the ball, and in-line with your target. The shorter, lower groove promotes proper ball position alignment, while the longer groove above it helps align your clubhead to your target.

HYDRAZIP

HydraZip for HALO XL Irons uses a dynamic blast system designed to maximize spin in wet or dry conditions, and from anywhere around the green. This proprietary spin technology ensures consistent performance in all conditions and from any lie.

In lower lofts (4i–7i), we use a rougher face blast to minimize excess spin for improved carry distances. Meanwhile, high-lofted clubs (8i–SW) receive a slightly smoother blast, to promote better spin consistency.

XL HEAD DESIGN

A larger, Hybrid-Iron profile allows us to shift more mass away from HALO XL's center. That's how we upped the MOI and put the Center of Gravity exactly where we want it. Out on the course, that gives you an XL amount of forgiveness, a high-launching ball flight, and straighter shots.

THREE SOLE TRANSITION

HALO XL uses a three-sole system designed to fit the differing long-, mid-, and short-Iron swings. Long Irons (4i–7i) feature GlideRail soles, which improve turf interaction and promote solid contact on sweeping swings. Short Irons (8i–9i) feature V-Shaped soles, designed to cut through turf so you can hit down on the ball without digging. And Wedges (PW–SW) feature Three-Tiered Soles for maximum forgiveness on pitches, chips, and bunker shots.

ACTION MASS CB

Action Mass CB places an 8-gram counterweight in the end of the shaft near the very top of your grip. The feel of added weight in your hands helps the club seem lighter, promoting a more stable, controlled backswing. It also helps promote a more inside swing path, squarer club face through impact, and, ultimately, straighter shots.
