Purple Pearl Urethane 78D

The Legend, Now Harder Hitting!

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.
