## Description

Pick up a NEW Obsession!
The Obsession and Obsession Tour have the same core shape; however, the Tour edition differential is .016 points lower, creating less flare, less hook, and a more controllable reaction compared to the regular Obsession.
OBSESSION
The Obsession has a new strong formula called Envy Solid CFI, where we’ve gone back to infusing the shell with carbon fiber. Featuring DOT technology, which allows you to drill anywhere which makes this ball even tougher.
