The outside of the soccer ball is typically made from one of two materials: PVC or Polyurethane. PVC is much more affordable and durable, and these are typically seen in training soccer balls because training balls go through much more of a continuous beating. Polyurethane balls are usually even softer than PVC balls and its ability to go where you want it to go is much better than the PVC balls. As a result, these are typically higher-end balls. However, there are still various ways to construct them, and not all PVC or polyurethane balls are created the same. Glossy coatings, which are very popular in the public fields with the kids and adults alike, are also very useful because they help reduce scuffing and the intake of water.
How Do I inflate my soccer balls? Soccer balls lose air pressure over time. Sometimes over a few days (soccer balls that use butyl bladders keep air pressure longer than balls that use latex bladders). Be sure to check the pressure frequently to make sure the ball is properly inflated. Therefore, invest in a good ball pump, have a supply of inflation needles and use a low pressure gauge to measure for proper inflation.
I purchased the soccer ball for my son as a gift. It came deflated so we filled it with air before boxing it. Upon opening it, it was deflated. It only held air for a few hours. I contacted the company and they immediately shipped out a new one without hassle that is holding air just fine. (I was very pleased with how prompt and pleasant they were!) It lights up very bright when hit or bounced and turns off on its own after a little while of not being hit or bounced. My kids all love it and play with it nightly. It is not stitched as a real soccer ball is, but is more of a heat fused soft plastic. It holds up just fine though to my 13 year old soccer player's kicks. We are all enjoying playing with it and happy with our purchase.
