Track Proof Pearl Bowling Ball

Release Date: 9/3/20


It’s been a long-time since we’ve tested a ball like the Proof.  A ball that looked great for everyone regardless of style and bowlers all over the world have confirmed this.  While the Proof had a hard time living up to it’s potential, it’s still known as a great ball, and we are excited to follow it up with the Proof Pearl, a shiny version that gives you the same great reaction, that’s just intended for more medium lane conditions.
