The Adidas Pelias (/ˈpiːliæs/ PEE-lee-ass, Greek: [peˈli.as]) was first used in the football events of the 2004 Summer Olympics, and was the official ball for all FIFA events in Europe in 2004.
The ball is made by Adidas, and was made using the same materials and construction as the Adidas Roteiro, the official match ball of the UEFA European Football Championship in 2004.
The panels of the ball were thermally bonded and makes use of Adidas' Power Balance Technology.
The original Pelias and the new Pelias 2 make use of the same basic design, with the differences mainly lying in the colour and thickness of the lines on the panels.
Each section of the design is based around a repeated Hexagon and 3 Pentagon pattern.
