The story behind this ball
Our design team created this hybrid ball after observing football players in action on the pitch.
This ball is a hybrid because its design combines the comfort of a machine-stitched ball with the durability of a hand-sewn one.
We also used a bladder with a special design (2 km of thread is wrapped around the bladder) to ensure lasting inflation and better sphericity
Maximum pressure loss test: here's what we do...
Here's how we test pressure loss: We inflate the ball to the recommended pressure (meaning 0.8 bar).
72 hours later, the ball must not have lost more than 15% of its pressure, meaning approx. 0.1 bar (FIFA Basic certification). The pressure after 72 hours must, therefore, be at approx. 0.7 bars.
This also means that it is quite normal for a ball to lose pressure after a few days.
A "round" ball?
Here's how we test sphericity:
Average measured variation: 1.8% max (FIFA Basic certification).
We measure the football's sphericity at 4500 different points and then examine any differences.
If the discrepancy is greater than 1.8 % (FIFA Basic Standard), our engineers are tasked with improving the sphericity to ensure a consistent bounce.
