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 (the seams are on the inside).
We've also used a special bladder (2 km of thread is wrapped around it) to ensure lasting inflation and better sphericity.
The durability of our balls
We've developed a tool for characterising the durability of our balls.
Defects that appear in use are identified and assessed through a series of laboratory tests.
These tests enable us to compare the overall strength of our footballs with those available on the market.
Our aim: to have the most durable products on the market.
Too light? Too heavy? The weight is standardised...
This ball weighs between 350 g and 390 g (size 4) and complies with official FIFA standards.
FIFA Basic approved.
How big is it? What's the circumference?
This ball measures between 63.5 cm and 66.0 cm (size 4) and complies with official FIFA standards.
FIFA Basic approved.
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.
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 bar.
This also means that it is quite normal for a ball to lose pressure after a few days.
We've also tested how much water the ball absorbs...
Here's how we test water absorption:
We simulate rainy playing conditions in a lab, leaving the ball to sit in 2 cm of water on a pivoting support whilst subjecting it to 250 compressions.
At the end of the test, the ball must have absorbed no more than 15% of its weight (FIFA Basic certification).
It's all about the bounce
Here's the bounce test:
The ball is dropped onto a steel plate 10 times from a height of 2 metres.
The bounce height must be between 115 and 155 cm with a maximum difference of 10 cm between the ball's highest and lowest bounce.
Not even a scratch!
The most stringent test we put this ball through is the shooting machine test.
The ball must resist 2,500 shoots against a concrete slope at 50 km/h at a distance of 2.5 m.
At the end of the test, we check:
- the ball's general state: stitching must withstand this test
- the circumference: must not have increased by more than 1.5 cm.
- the sphericity: it must not have varied by over 1.8%
- the pressure: loss of pressure must not exceed 12.5%.
