Soccer balls have several panels that influence their flight characteristics and the amount of control a player can have while playing. International soccer competitions use a 32-panel ball. Major leagues use an 18-panel ball and indoor leagues use a 6-panel ball. High-end soccer balls have hand-stitched panels with a synthetic thread. A low-cost one for practice and training will usually have its panels glued together.
Size 5 is the official size for professional matches. Therefore, this ball is only available in this size. Do not use this soccer ball on concreted areas. Its unique rubber uses Puma Airlock Valve Technology (PAL) in order to facilitate proper airlock technology. This ball features Perimeter Balance Technology (PBT) which enables it to maintain impressive flight characteristics. https://www.youtube.com/watch?v=j2Xn84L3Kcs
