The story behind this ball
This hybrid ball was designed based on observations of soccer players on the field.
This hybrid ball combines the comfort of a machine-stitched ball with the durability of a hand-sewn one.
Two kilometres of thread is wrapped around the bladder to ensure lasting pressure and better sphericity.
Too light? Too heavy? The weight is standardized.
This ball complies with official FIFA standards and weighs between 410 g and 450 g in size 5.
FIFA Basic approved.
How big is it? What’s the circumference?
This ball measures between 68.0 cm and 70.0 cm 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 ball’s sphericity at 4,500 different points and then examine any discrepancies.
If the discrepancy is greater than 1.8% (FIFA Basic standard), our engineers work on 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 (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 (FIFA Basic certification). 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.
We also test how much water the ball absorbs.
Here’s how we test water absorption:
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.
At the end of the test, the ball absorbed no more than 10% of its initial 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 125 and 155 cm, with a maximum difference of 10 cm between the ball’s highest and lowest bounce.
Not even a scratch!
The most strenuous test we put this ball through is the shooting machine test.
The ball must withstand 2,500 shots against an inclined concrete surface at 50 km/h from 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 1.8%.
Pressure: Pressure loss must not exceed 1.5 psi.
