They tried to hold Hammer urethane back. It only made us push harder. Introducing the Purple Pearl Urethane 78D — built around the all-new Super LED core, more than doubling the differential and flare potential while keeping Hammer's proven thick-shell technology.

The result is a reaction closer than ever to the infamous Purple Pearl Urethane, now delivered in a harder 78D formulation. Consider it back — as good as ever, just less restricted by rules and red tape.

Who It's For

• Urethane players — more diff and flare than any Hammer urethane before it.
• Short-pattern & control bowlers — thick-shell urethane predictability with added shape.
• Purple Pearl fans — the legend reborn in a harder 78D formula.
