Update: While this ball was ruined in 3 days of use, the customer service team contacted me quickly and offered to send another product to try from this company. I thought this was very generous and warrants another try. With 3 kids now in soccer, I will update this review upon receipt of the next ball. (I added a star to the rating because they seem to want to stand by their company.)
Sizing is very important in selecting a soccer ball.  For the purposes of this article, I will mostly concentrate on size 5 outdoor soccer balls, but I will quickly go over the various sizes and let you know what they are used for.  Size 1 soccer balls, or skill balls (also known as mini balls), are primarily used by youth players that are just being introduced to the game.  These are typically 1-3-year-olds.  Another use for Size 1 balls is for older players to learn to juggle.  It is much harder to juggle a size 1, so instead of using a hacky sack, they use a skill ball.  This is done because the texture and materials are similar.  Size 3 balls are slightly bigger than size 1 and are used for ages four through seven.  They do this so that the ball isn’t too big in comparison to the players.  Size 4 balls are used for age eight through eleven.  Size 4s are smaller than size 5, which is used for everyone past the age of eleven.  This is the same size that the professionals use.  Making sure that you have the proper ball is just as important as picking out which materials one has.
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
