The most iconic in-house kits ever A tradition shared by all football leagues around the world

Every time our eyes fall on a football jersey, especially those from the major European and world leagues, we expect to see logos like the Swoosh of Nike, the Three Stripes of adidas, the diamond of Umbro, the initials of New Balance, or many others, like the puma of the eponymous brand, the runbird of Mizuno, or the overlapping arches of Under Armour. The partnerships that arise between football clubs and suppliers manage to delineate the visual identity of a company, marking, at least from an aesthetic point of view, entire football eras.

Moving to Spain, one of the most memorable examples is that of Real Betis Balompié, a club currently sponsored by Hummel which dreams of expanding in LaLiga by conquering Barcelona's jersey. The in-house kits of the Seville club demonstrate how these can turn into completely self-referential logos: on the uniforms used during that biennium, in fact, the acronym RBB appeared, referring precisely to the official name of the team. In short, the technical sponsor can sometimes turn into a real double logo.
