I decided to try to contact Kan Jam, since I was more interested in the possibility of an exchange than a return. In my experience, if a company will honor an exchange, some of the time, they won't require that you send the original product back. But I couldn't find any direct contact info for Kan Jam and decided to just open up a Return Request through Amazon. I did say in the comments that I would prefer an exchange over a return, but I
A ball is just a ball, right? Well, it’s not quite that simple any more. Some important things to consider are what the ball is constructed of, what material is used for the lining or bladder and, to state the obvious, the size of ball you require, which will depend on the ages of the players and the ball’s intended use, be it for training or match games.
Much like PU or TPU for soccer ball casings, rubber is considered the best of both worlds for soccer ball bladders when it comes to striking a balance between responsiveness and air retention. Oddly enough, this balance does not actually inspire a greater adoption by either manufacturers or players, and as such, soccer balls with rubber bladders are less popular.
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.
Our main intention of finding the official match balls was to help you find a solution which is good in quality, and you can use it for league plays. The process was tough we must say. Not all the replica balls have good quality. That is why we were very choosy in the process. We filtered the balls not only based on our experience but also based on the experience of other users.
Latex bladders are one of the best materials when it comes to ball construction. However, with latex bladders, air won’t last as long as butyl bladders and will need more attention for proper inflation. Butyl-blend bladders hold in the air much better, but they are harder and less receptive in play. Mid-priced balls will usually have a mix of butyl and rubber. https://www.youtube.com/watch?v=c1SVcjYY6TE
