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 and check patterns, crafting a fresh narrative by reimagining the aesthetic of security personnel, staying true to the football-driven DNA of the Manchester-based brand. Features include 100% polyester construction, a loose fit, gingham check pattern, elasticated drawstring waistband, two side pockets, embroidered logo at the front, reinforced double knee, woven flag label at the side, and made in Italy.
