The addition of Alpha Premier Hybrid, a non-HK22-based cover, creates traction in oil while maintaining the predictable continuation that made the original Combat so effective. Paired again with the Rampart core, this new 2000 grit-finish asymmetric hybrid reads the midlane earlier and more aggressively, providing a heavier roll with relentless motion through the pins. We created Combat Hybrid to be that crucial step up in motion and traction from the original. Similar in shape, but more of it. When lanes get tougher and transition demands a controlled yet continuous shape, Combat Hybrid is your most dependable weapon for scoring.
