While the ball features high-quality materials, the focus with this ball is all the smart features and less about the physical make-up of the ball, which doesn’t come in handy when you’re researching! What I did find with this ball is that it’s match quality and built to last. It’s also available in sizes 4 or 5 for multiple ages and training levels.
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
