Another imprint you’ll find on your Adidas 2016 MLS Official Match Ball, is the FIFA quality seal. As you recall, the FIFA testing involves many aspects of testing in order to pass certification and earn this imprint. This ball passed in all categories including circumference, sphericity, rebound, water absorption, weight, loss of pressure, and shape/size retention.
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
