Main Material

It's important that young soccer players use the right ball size, no matter their age.
Size 3 for < 9 year olds.

Size 4 between 9 and 12 years.
Size 5 for over 12 year olds.

In addition, we have conducted numerous lab and field tests to guarantee the ball's ability to withstand every hit.

The story behind this ball

Ball weight: Between 410 and 450 g (Size 5)Between 350 and 390 g (Size 4)Between 290 and 335 g (Size 3)

Too light? Too heavy? The weight is standardized.


Ball circumference: Between 68 and 70 cm (26.7' and 27.6') (size 5).Between 63.5 and 66 cm (25' and 26') (Size 4).Between 58.0 and 60.0 cm (22.8' and 23.6') (Size 3).

How big is it? What’s the circumference?

Average measured variation: maximum of 2%.
We measure the ball’s sphericity at 4,500 different points and then examine any discrepancies. 
If the discrepancy is greater than 2% (FIFA Pro Standard), our engineers work on improving the sphericity to ensure a consistent bounce.

A round ball?

We inflate the ball to the recommended pressure (11.6 psi).
The ball cannot lose more than 15% of its pressure over the next 72 hours, meaning a maximum pressure loss of 1.5 psi. The pressure after 72 hours must be approximately 10.1 psi.
This also means that it’s quite normal for a ball to lose pressure after a few days.

Maximum pressure loss test: here’s what we do.

To simulate rainy playing conditions in a lab, we put the ball in 2 cm of water on a pivoting support and subjected it to 250 compressions.
By the end of the test, the ball must not have absorbed more than 15% of its weight. For this ball, it means a maximum of 65 g.

We’ve also tested how much water the ball absorbs.

Between 125 and 155 cm (size 5) with a maximum difference of 10 cm between the ball's highest and lowest bounce. Each ball is dropped 10 times on a steel plate from a height of 2 m.Between 115 and 155 cm (42.3' and 61.0') for size 3 and size 4 balls.

It’s all about the bounce

The most demanding test this ball undergoes is the machine shot test.
The ball must resist up to 2,500 shots against an inclined flat concrete slab at 50 km/h at a distance of 2.5 m.
At the end of the test, we check:
- The ball’s general condition: Stitching must remain intact.
- Circumference: Must not have varied by more than 1.5 cm.

- Sphericity: Must not have varied by more than 2%.
- Air pressure: Pressure loss must not exceed 15%

Not even a scratch!
