HUGO BOSS returned as the title sponsor for the BOSS OPEN 2023 at the Weissenhof, following the success of the ATP tournament's 2022 rebrand. BOSS brand ambassador Matteo Berrettini, who took the men’s singles title at the BOSS OPEN 2022 was, for the first time, dressed from head to toe in signature BOSS colors. The tournament also marked the release of his new collaborative capsule collection with BOSS, featuring a polo shirt, shorts, a baseball cap, and an exclusive design of the GEL-RESOLUTION™ 9 tennis shoe in collaboration with ASICS. Attendees had the opportunity to shop the collection at a pop-up store at the Weissenhof, along with the award-winning BOSS x HeiQ AeoniQ™ polo shirt, made from revolutionary cellulosic yarn. The tournament prominently displayed BOSS branding throughout the venue, with ball kids and line umpires donning custom BOSS uniforms.
