London, UK – June 2026 – Champion and JAB today announce the launch of a new collaborative capsule collection and immersive one-night-only experience, taking place on 11th June at SpaceUnlocked in Shoreditch.
Blending Champion’s legacy in heritage sportswear with JAB’s contemporary performance culture and nostalgic boxing aesthetic, the collaboration introduces a limited-edition apparel collection inspired by the golden era of boxing and mid-century athletic design.
The collection will debut exclusively at the Shoreditch pop-up before launching online via JAB’s Shopify store.
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.
The capsule collection 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.
Hannah Steele, Brand Director at JAB, said:
“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.”
Chris Haggarty, Champion Europe, 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.”
The activation also marks the first public moment for JAB’s forthcoming EC1 performance club, opening Autumn 2026 in Moorgate. 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.
The capsule collection launches Wednesday 11 June, with prices ranging from £32-£75.
