Adidas spared little expense with this soccer ball and made sure that the materials used could pass almost any standard for grass fields. First, the casing is made of polyurethane, providing a great balance between responsiveness and durability-though they further increased the responsiveness with 3D textures. The bladder is made out of butyl, so you will not have to worry about constantly reinflating it, while the ball is lined with soft and water-resistant polyester.
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
