Paul & Shark is a famous sportswear company based in Italy which originates in a small hamlet near the northern city of Milan.

In the UK it is commonplace in the casual football scene / style, especially with followers of northern clubs, most notiably Manchester United, Everton and Sunderland. It does not have quite the same notoriority as Stone Island does, but Paul and Shark has largely become a logo recognisable for members of hooligan gangs / firms.
