Early footballs began as animal bladders or stomachs that would easily fall apart if kicked too much. Improvements became possible in the 19th century with the introduction of rubber and discoveries of vulcanization by Charles Goodyear. The modern 32-panel ball design was developed in 1962 by Eigil Nielsen, and technological research continues today to develop footballs with improved performance. The 32-panel ball design was soon overcome by 24-panel balls as well as 42-panel balls, both of which improved performance compared to before, in 2007.
The secret to the authentic movements on a rebound with this ball is the inclusion of an SBR foam layer underneath the PU cover. This allows the power of a pass or shot to be transferred with more accuracy. It keeps the ball somewhat soft to the touch, but creates a realistic movement which allows players to develop an ability to start reading the game with accuracy without the need to purchase an expensive premium match soccer ball. It comes in all of the standard sizes and offers 4 unique design options, allowing players of any age or ability to begin working on their soccer skills.
Though, a ball designed to be played virtually anywhere will have to sacrifice something to achieve that versatility. For the Brasilia, that sacrifice comes in the form of responsiveness. While the glossy finish may offer some protection, it also reduces your touch with the ball. A bladder made out of synthetic rubber-not to mention that TPU is only okay when it comes to touch in the first place, further compounds this effect.
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
