FEATURES:

• GLIDERAIL
  Three large, tapered rails along the sole of each HALO XL Hybrid deliver optimal ball striking and clean turf interaction. Each rail is designed to gently glide straight through the turf so you can maintain clubhead speed and keep a square face through impact. Plus, they're super helpful from the rough, or, any tough lie.
• MAINFRAME XL
  Every HALO XL Hybrid delivers max distance with added forgiveness, thanks to MainFrame XL. MainFrame XL uses a variable thickness face pattern that expands and reshapes the sweet spot for more energy transfer across the face. Inside the clubhead, Al helped us figure out the best spot to place weight pads for long, high-launching ball flight.
• XL HEAD DESIGN
  These reworked, XL Head Designs allow us to shift more mass away from the club's center. This ups the MOI, delivering more forgiveness and consistency on every strike. They also feature our HiBore Crown Step, which brings the Center of Gravity even lower in the clubhead for longer, straighter ball flight. Plus, deeper faces create a larger, more forgiving striking area.
• REBOUND FRAME
  Unlike other clubs, HALO XL Hybrids have the unique ability to flex twice at impact thanks to Rebound Frame. Like a spring within a spring, Rebound Frame adds another ring of flexibility that sits just behind the face, supported by extra stiffness in the rear of the clubhead. At impact, these dual flex zones activate simultaneously, increasing the amount of energy transferred into the ball.
• 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.
