If you are unsure of which size to get your child, I will recommend what size I think based off real-world use. The size 3 is good for any child until about first grade or second grade, which is when a child should move into a size 4. The size 4 should last until they get to middle school (around 6th or 7th grade), and then they would move into the adult official size 5.
Wilson is a classic sports company that gives you just about everything that you need in a soccer ball. This ball has a synthetic leather cover which is soft to the kick, but also has enhanced ball durability. It has a butyl rubber bladder to hold the air which gives the ball its shape and and retains the air. This has the classic black and white panel colors.
The exclusive design of the exterior hides a football manufactured in specially-developed Japanese TEIJIN microfibre, which makes the ball seem significantly softer than its predecessor. Without compromising on material thickness or adding foam, we have achieved a thoroughly tested feeling of liveliness and lightness – while naturally also preserving the good characteristics such as control and stability that have always characterised a BRILLANT SUPER.The material may be Japanese but BRILLANT SUPER is produced as always by our year-long supplier in Pakistan. The ball is sewn by hand and produced in quality materials from its innermost to its outermost layers. The Zero-Wing bladder ensures that the ball remains in constant balance throughout its flight through the air and a Double-Lock butyl valve ensures that it is practically airtight.
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
