The idea of the Humphrey brothers, who founded Umbro in 1924, was to put quality, fit and purpose at the heart of their clothing to ensure high performance on the pitch. So many clubs followed that by the end of the 1960s, 85% of the English league were wearing Umbro, leading to the expansion of the catalogue into other sports and, later, lifestyle products. The Double Diamond brand became an icon of British sportswear, thanks to an approach that made football uniforms identifiable with an emerging culture, such as the iconic multicoloured nylon shorts that peaked in the 1980s and 1990s, recognised as the Umbro Neon Movement. In recent years, as well as continuing to sponsor teams and players, Umbro has entered the streetwear trend, collaborating with Palace, Aries, Off-White, Polartec, Raeburn and many others.
