Purple Pearl Urethane 78d Hammer

They’ve done everything they can to hold Hammer urethane back. Rule changes. Restrictions. Limits. None of it stopped us. It only made us push harder. While governing bodies around the world may not be ready for what’s next, competitive bowlers are.
 
Introducing the  Purple Pearl Urethane 78D. Built around the all-new Super LED core, this design more than doubles the differential and flare potential while maintaining 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.
