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.
Latex bladders are one of the best materials when it comes to ball construction. However, with latex bladders, air won’t last as long as butyl bladders and will need more attention for proper inflation. Butyl-blend bladders hold in the air much better, but they are harder and less receptive in play. Mid-priced balls will usually have a mix of butyl and rubber. https://www.youtube.com/watch?v=c1SVcjYY6TE
