In competitive sport, opposing teams are required to wear different colour shirts.

In some sports, teams must have two sets of uniform shirts with different colours to prevent a colour clash.

In SUB Football, this problem is overcome by the use of bibs which are provided by SUB Football Network and which form part of each referee's equipment.

There are 10 outfield players bibs and 2 GK bibs for the goalkeepers.

The Referee decides which team wears the bibs.
