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 10% of its weight (FIFA Quality Pro standard). This is one of the advantages of the thermobonded process; water absorption is limited in comparison to other processes (machine-stitched for example)
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 135 and 155 cm with a maximum difference of 10 cm between the ball's highest and lowest bounce.
Too light? Too heavy? The weight is standardised...
This ball weighs between 420 g and 445 g (size 5) and complies with official FIFA standards.

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 1.0 cm.
- the sphericity: it must not have varied by over 1.5%
- the pressure: loss of pressure must not exceed 10.0%.
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.
Exclusive to Kipsta
We know that, in matches, the little details make all the difference. For this Pro ball, we wanted to create an ultra-reliable ball. We focused on the stability and feel of the ball in play. To do this, we tested different types of outer panelling and chose the one which showed the best results. This 12-panel design combined with the embossed lines is exclusive to Kipsta.
A "round" ball?
Here's how we test sphericity:
Average measured variation: 1.5% max (FIFA Quality Pro standard).
We measure the football's sphericity at 4500 different points and then examine any differences.
When the discrepancy is greater than 1.5% (FIFA Quality Pro Standard), our engineers are tasked with improving the sphericity to ensure consistent rebound.
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 Quality Pro 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.
The story behind our range of balls
Our range of balls has been co-designed with 244 European footballers. This community helped us to pick the colours and names so that it's easy to see the difference between the models.
These balls are FIFA approved and designed to meet different levels of technical requirement (Training, Club, Match, Pro Ball).
Their increased durability and better feel bring them ever closer to the official ball that graces the pitches of the Ligue 1 McDonald's and Ligue 2 BKT.
The story behind this ball
For this FIFA Quality Pro football, our designers have used thermobonding technology (seamless) to guarantee perfect sphericity and more precise shots. In addition, this technology ensures better waterproofing while training in the rain. Lastly, to make the ball as round as possible, we've chosen a laminated bladder (there's a band of fabric glued to the bladder).
A beach ball?
We know that a stable trajectory is important, especially for field players kicking long balls and for goalkeepers sending the ball down the pitch. Balls are traditionally made with 32 panels, but we've designed this Pro ball using 12 identical panels. These 12 panels are also thermobonded and have special grooves in them, along with a microfibre fabric. This significantly improves the ball's stability and makes it more enjoyable to play with.
