This is much like the kind of balls that I often buy and play with. This is a training ball, but don’t let that fool you into thinking that means it is low quality. It is machine stitched, meaning it is mass-produced and has a nylon interior, making the ball last a long time as you practice and do your daily drills. It also has a butyl bladder and is polyurethane so that it will stay inflated longer. It has a really catchy green and black design and I’m sure all the kids would absolutely love to have this ball (or two) for the great price!
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
