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. Made from 65% Cotton and 35% Polyester, this shirt features ripstop fabric, a boxy fit, classic collar, concealed button closure, embroidered logo, and crest logo at the sleeves. This is a Slam Jam exclusive.
