Enjoy the game. The Chrome Tour Retro Collection pays homage to Callaways first-ever golf ball, Rule 35.

Released in 2000, the Callaway Rule 35 golf balls marked the companys innovative entry into the ball market with two simple, golfer-focused options: Blue for softer feel and Red for a firmer feel. At the time, Rule 35 was Callaways fictional addition to the official 34 rules of golf: Enjoy the Game. This limited-edition ball brings the iconic Rule 35 design to the 2026 Chrome Tour, now paired with advanced ball technologies for exceptional ball speed, consistent flight, and precise greenside control.
