perfecting your football technique.
For this F100 hybrid football, our design teams have chosen to use an inner foam covering for extra playing comfort, as well as making stitching invisible for greater durability.
The ball stitching is inside, making it invisible and more durable.
We have placed foam panels on the outer cover for your playing comfort.
Lasting air retention
Guaranteed to keep ball pressure for longer thanks to Butyl et Latex bladder.
Consistent rebound thanks to the quality of bladder and outer cover
Bladder wrapped in a thread to maintain its shape and ensure greater accuracy

- Our design team watched football players in action on the pitch to develop this Hybrid ball. This ball is a hybrid due to a concept that combines the comfort of machine sewing with the durability of hand sewing. We also used a bladder with thread winding (2 km of thread is wrapped around the bladder) to ensure lasting inflation and better sphericity.
- Between 420 and 445g (Size 5)
- Between 68.5 and 69.5 g (Size 5).
- Average measured variation: maximum 1.5% We measure the football's sphericity at 16 different points and take a look at the recorded discrepancies. When the discrepancy is greater than 1.5% (FIFA PRO Standard), our engineers are tasked with improving the sphericity to ensure consistent rebound.
- We inflate the ball to the recommended pressure (meaning 0.8 bar). 72 hours later, the ball must not lose more than 15% of its pressure, meaning approx. 0.1 bar. 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 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. By the end of the test, the ball must not have absorbed more than 15% of its weight, meaning approx. 60 g for this F100 in size 5.
- Between 135 and 155cm with a maximum difference of 10cm between the ball's highest and lowest bounce. Each ball is dropped 10 times on a steel plate from a height of 2 metres.
- The most stringent test we put this ball through is the shooting machine test. Withstands up to 2500 shots against an inclined concrete surface 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: it must not have increased by more than 1.5 cm - the sphericity: it must not have varied by over 1.5% - the pressure: the ball's loss of pressure must not exceed 0.1 bar
