Ozzy Osbourne is stepping onto the grappling mats. A new officially licensed collaboration with Half Sumo, a New York combat culture brand, arrives Friday, Oct. 23, and includes the first jiu-jitsu apparel ever released under the Ozzy Osbourne name. The headliners are the “Crazy Train” No-Gi Set, a custom rashguard and shorts combo, and the “Prince Of Darkness” Streetwear Set. Early access signups are open now here.
Ozzy Osbourne‘s name has covered records, arena stages, festival posters and TV screens for more than 50 years. It now lands in Brazilian Jiu-Jitsu, a fast-growing sport practiced in academies from Brooklyn to Birmingham to Rio de Janeiro. The family already has a foot in the door, as Jack Osbourne took up jiu-jitsu in his thirties, trains regularly and holds a purple belt. Every piece in the collection is designed to survive hard training and a lot of sweat.
Half Sumo argues that metal and jiu-jitsu share the same DNA. Outsiders built both, and both reward obsession, repetition and the stubborn habit of showing up when it hurts. Ozzy Osbourne fit that mold as a working-class kid from Aston, Birmingham, who helped invent heavy metal with Black Sabbath, reinvented himself as a solo star and spent a lifetime proving the doubters wrong. Founded in 2018, Half Sumo has built its identity around that same underdog who refuses to tap.
The collection arrives just over a year after Ozzy Osbourne‘s farewell “Back To The Beginning” show at Villa Park and his death in July 2025. It carries the approval of the Ozzy Osbourne estate and is pitched as a living tribute. Half Sumo runs the late singer’s imagery through its own style of Ukiyo-e-inspired artwork, Irezumi tattoo tradition and streetwear, with the goal of introducing a new generation of fighters to the Prince of Darkness and introducing the brand to metal fans.
“We both grew up as lifelong Ozzy fans,” said Half Sumo co-founders Luigi Scarcella and Alberto Marchetti. “Having the opportunity to collaborate on this project is a genuine honor for us and a way to celebrate his incredible legacy. Ozzy was the original underdog, and jiu-jitsu is built on that same spirit of the smaller person who refuses to quit.”
Here is what launches Friday, Oct. 23.
The “Crazy Train” No-Gi Set pairs a fully sublimated rashguard with matching grappling shorts, made for both training and competition. The rashguard is covered in red, purple and bone white artwork featuring skulls, bats, the classic Ozzy logo and nods to “Mr. Crowley,” “Bark At The Moon,” “No More Tears,” “War Pigs” and Blizzard Of Ozz, all hand-drawn in the Half Sumo illustration style. The shorts center on a giant purple bat-wing Ozzy logo over the same all-over art, with Half Sumo lettering running down the leg.
The “Prince Of Darkness” Streetwear Set is a limited run for life off the mats. The zip-up hoodie sports a bat-wing Ozzy emblem topped with the Half Sumo crest, while the graphic tees include a fanged, vampire-style Ozzysurrounded by bats, song titles and Japanese lettering. More items will be revealed at launch.
Everything is produced in strictly limited quantities with no restocks planned, so once it sells out, it is gone. Half Sumo has set up a dedicated landing page with the collaboration artwork, where fans can register for early access here.
The day after launch, Half Sumo will host an Ozzy-themed Halloween pop-up on Saturday, Oct. 24 at its headquarters, 247 Water Street in Brooklyn, N.Y. The full collection will be available to buy in person.
Marchetti and Scarcella founded Half Sumo in New York City in 2018 as an independent brand born on the mats and built around the culture, art and lifestyle surrounding them. Marchetti is a 4th-degree Brazilian Jiu-Jitsu black belt under pioneer Renzo Gracie and a longtime presence in martial arts apparel and fashion. Scarcella is a three-time USA Full-Contact Kyokushin Karate Champion who represented the United States at the World Tournament in Tokyo in 2019 and 2023, and he is the artist behind the brand’s look.
The company also has deep roots in the community. During the pandemic, Scarcella designed custom gear for more than 100 academies worldwide, and all profits went to the academies, raising hundreds of thousands of dollars for gyms from New York to Tokyo.
The brand’s visual style pulls from Irezumi, Ukiyo-e and Japanese folklore, plus Western iconography, tattoo culture, graffiti, street art and underground illustration, all filtered through its own contemporary lens. Its guiding idea is that technique beats size, and that David can still take down Goliath. Over the years, Half Sumo has teamed up with adidas, Coca-Cola, Megadeth, Netflix and others across martial arts, sports, music and pop culture.
