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, while staying true to the football-driven DNA of the Manchester-based brand. Constructed from 100% polyester, featuring a mesh fabric, boxy fit, classic collar, two-button placket, crest logo at the chest, and an all-over printed graphic.
