The outer casing of a soccer ball is composed of panels made from synthetic materials, such as PVC, PU, or a combination, sewn or glued together. Soccer ball casings are rarely leather anymore, since leather tends to absorb moisture making the ball heavier and not perform as well. The number of panels or sections of the outer casing varies according to design. Most professional soccer balls are the 32-panel design. More panels mean a rounder and stabler ball, and a more accurate flight.
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
