Cal South Referee Program & Official Sports Announce Partnership

  • OSI named Exclusive Provider of Cal South logo-branded referee gear
  • New online Cal South Referee Store will go live on April 1, 2024

(Monday, March 18, 2024) – The Cal South Referee Program and Official Sports International (OSI) are pleased to announce a formal partnership to support referees throughout the Southern California area.

Through this collaboration, Official Sports International will serve as the Exclusive Provider to Cal South referees of official USSF uniform and Cal South logo-branded gear kits, as well as supporting Cal South’s multiple referee development initiatives. OSI’s turn-key order process will make it quick, easy, and cost-effective for new referees to get the equipment they need to be successful on the field for years to come.


Our referee program is a leader among referee development and training throughout the U.S.,” said Juan Guzman, Cal South State Referee Administrator and a former FIFA and MLS referee. “Continuing our mission to provide safe playing environments for our soccer community, we have ascertained that a referee’s image must be professional in appearance to create acceptance and trust on and off the field. The high quality of Official Sports’ referee apparel and customer service is exactly what we need to provide the best for our referees, and their online store experience specifically customized for our membership is on the cutting edge of the industry.”

“We are honored to partner with the Cal South Referee Program, and to work with Juan and his team to bring quality apparel, equipment, and customer service to their membership,” said Julie Tobin, OSI VP Strategic Partnerships & Marketing. “As the official Technical Partner of the U.S. Soccer Referee Department, our custom Cal South Referee USSF starter kits will provide new referees with the official USSF uniform that will serve them well for years to come.”


Official Sports International is a family-founded, female-owned and operated company that has exclusively served the soccer referee community for the past 40 years. They have been the exclusive technical partner and uniform provider to U.S. Soccer and NISOA (college soccer) for decades. They have an extensive, high-quality product line, live customer service, and 24/7 online ordering.

The new Cal South Referee Store created by Official Sports is scheduled to go live on April 1, 2024. The link for the new store will be provided to all Cal South referees and announced on calsouth.com on that date once the site is live.
