The name of the + Teamgeist ball founders wanted to remind you that one of the most important components of success at the World Cup - the team spirit. Translated from the German word team means "Team" and geist - "spirit". The ball 14 is made of exterior structural panels, resulting in the reduction of joints 60%. This initiative is aimed at improving the accuracy of impact and improved ball control. The design has undergone significant changes as compared to its predecessor. As for the plus sign before the name of the ball, then it was done due to the fact that the regular expression teamgeist alone could not be used as a trade mark.
