Bought this as a birthday gift for a 10-yr old boy who loves soccer. The ball is made of a durable rubber material, but it is official weight and size for those who are wondering. The rubber exterior gives the ball more bounce than a typical "official" soccer ball, but IMO it makes the ball more fun to kick around as well as more durable. There are 2 LED lights inside the ball which illuminate when the ball is kicked or tossed onto the ground. LED's shut off automatically after about a minute of inactivity which helps conserve the batteries. No more calling off the soccer game when the sun sets, this ball makes it possible to play in pitch dark conditions and is a blast to kick around. Fun for all ages, kids as well as adults. Great buy, 5 stars.
Another imprint you’ll find on your Adidas 2016 MLS Official Match Ball, is the FIFA quality seal. As you recall, the FIFA testing involves many aspects of testing in order to pass certification and earn this imprint. This ball passed in all categories including circumference, sphericity, rebound, water absorption, weight, loss of pressure, and shape/size retention.
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
