Founded in 1924 by brothers Harold and Wallace Humphreys, started as a family project and quickly became a leading sportswear brand for footballers. The Manchester-based brand, known for its iconic double-diamond logo, has remained a staple both on the field and in everyday streetwear. Umbro offers a wide range of versatile collections, blending classic sportswear with contemporary styles. With a deep-rooted passion for sports in every design, Umbro continues to build on its rich legacy, winning fans across generations.

For Spring / Summer 2025, Slam Jam and Umbro introduce a new collection inspired by stadium security, seamlessly blending formalwear with sportswear in their signature style. Rooted in British culture, the collection pays homage to heraldry, check patterns, and crafts a fresh narrative by reimagining the aesthetic of security personnel, staying true to the football-driven DNA of the Manchester-based brand.
