A pair of vintage Umbro black synthetic tracksuit bottoms

A pair of athletic training trousers by the British sportswear brand Umbro. The garment is constructed from a matte black synthetic fabric and features an elasticated waistband and elasticated ankle cuffs. The cuffs are equipped with a drawstring cord and a plastic toggle adjuster. A fine white piping detail is visible along the outer side seam. The upper left thigh is detailed with an embroidered white Umbro double diamond logo. This piece is consistent with British athletic apparel from the late 20th century.
