Beginning with the 2018-19 season, Zenni's brand logo was sewn onto the left breast of all editions of the Chicago Bulls jerseys, which debuted on Oct. 18 when the team visited the Philadelphia 76ers for their season opener. The jersey made its first home court appearance at the United Center on Oct. 20 when the Bulls hosted the Detroit Pistons.

To celebrate their new partnership on Oct. 16 the Bulls and Zenni hosted more than 100 of Zenni's top Chicago area customers at a launch event in the United Center atrium, where they heard from Michael Reinsdorf and Zenni executives and enjoyed an exclusive meet & greet session with new Zenni Bulls ambassadors Zach LaVine, Lauri Markkanen and Robin Lopez. These special Zenni fans were welcomed by members of the Bulls staff and the team's mascot, Benny the Bull, all wearing Zenni glasses. They were treated to performances by Bulls entertainers, and viewed social content created for the announcement, including a video piece by Chicago artist Travis Ramos Brooks that creatively melds Zenni glasses with Bulls imagery and photos of Bulls players/fans wearing Bulls colored Zenni frames.
