The cooperation between Ekstraklasa with adidas is already in its sixth consecutive season and during this period we've used seven balls with the logo of the highest Polish football league. The first one was Brazuca, and since February 2020 the official ball of the league is Uniforia.

The last agreement was valid until the end of the 2019/20 season and both parties have already agreed to extend the cooperation. The new contract will be valid until the end of the 2024/25 season, that is for five consecutive years.
