## Description

THE NEXT EVOLUTION OF TOUR CONTROL.
The Zero Mercy Tour continues Hammer’s legacy of benchmark performance, following in the footsteps of favorites like the Obsession Tour, Envy Tour, and Effect Tour. By popular demand, we’ve brought back the proven core from the Obsession and Envy Tour series and paired it with a first-of-its-kind coverstock innovation.
For the first time, the HK22C² additives that helped make the Zero Mercy line one of Hammer’s biggest recent successes have been infused into a Tour cover formulation. The result is the perfect blend of traction and control—strong enough to handle heavier oil volumes while maintaining the smooth, predictable motion that Tour ball enthusiasts love. It reads the lane with confidence, handles volume with ease, and continues through the pins without losing energy downlane. The Zero Mercy Tour combines proven Tour performance with the next evolution of Hammer technology, creating a ball that feels familiar while delivering something entirely new.
