## Description

Not All Spare Balls Are Created Equal!
Hammer's new performance spare, the Tough, brings together a touch of new technology wrapped around a bit of old. By combining our new Polythane coverstock with a traditional pancake core, featuring carbon fiber, Hammer brings you the toughest spare ball ever produced. We're backing it up with a three year warranty.
POLYTHANE
We developed our latest coverstock formulation with one thought in mind: durability. Our new Polythane cover offers the performance of a polyester ball with the durability of a urethane ball.
PANCAKE CORE
This is the traditional core design found in the typical spare ball, but with carbon fiber added. It features a high RG and low differential to keep flare and hook potential low.
