Champion teams up with JAB for exclusive boxing-inspired collection and pop-up

US sportswear giant Champion is joining forces with boxing training and sports performance company JAB on a limited-edition capsule collection, set to be launched at a pop-up event at SpaceUnlocked in London’s Shoreditch on 11 June.

The capsule collection, which is inspired by the golden era of boxing and mid-century athletic design, reflects both brands’ shared approach to performance and style, combining “elevated athletic silhouettes with vintage-inspired detailing and relaxed tailoring” - intended to move fluidly between training and everyday wear.

Designed as an “immersive brand world” rather than a traditional retail launch, the Shoreditch experience will transform SpaceUnlocked into a nostalgic boxing environment featuring a co-branded boxing ring, campaign installations, vintage-inspired memorabilia displays and a pop-up bar serving complimentary electrolyte cocktails.

Throughout the evening, guests will also be able to participate in JAB-led boxing classes hosted within the venue’s fully equipped basement training space, bringing the club experience into the activation itself.

Champion Brand & Marketing Director EMEA, Chris Haggarty, said: “Champion has always been rooted in sport, but just as importantly in the culture that surrounds it. This collaboration with JAB felt instinctive. There’s a shared respect for boxing’s heritage and a clear, modern perspective on how performance lives today.

“The capsule reflects that balance - pieces that honour our legacy while speaking to a new generation moving fluidly between training, community and everyday life.”

Hannah Steele, Brand Director at JAB, added: “There was an immediate connection between Champion and JAB. Both brands are rooted in the heritage of boxing and that nostalgic energy from the sport’s golden era.

“We wanted the collection to feel authentic to that world - timeless, worn-in and performance-led, but still elevated enough to live beyond the gym.”

The collection launch comes ahead of JAB opening its first dedicated “performance club” in London’s Moorgate in autumn 2026.

The new 20,000 sq ft destination will significantly expand JAB’s current offering, introducing dedicated boxing studios, an open performance gym, reformer Pilates, elevated recovery facilities, restaurant-led hospitality, and expanded wellness spaces designed around modern athletic culture.

Following the Shoreditch event, the Champion x JAB collection will launch online via JAB’s Shopify store, with prices ranging from £32-£75.
