Made for
For this F100 hybrid football, our design teams chose to use an foam inner cover for extra comfort during play and invisible stitching for greater durability.

Technical Information

1
Design
Our design team watched football players in action on the pitch to develop this Hybrid ball. This football 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 the thread is wrapped around the bladder) to ensure lasting inflation and better sphericity.

Weight
Between 420 and 445g (Size 5)
3
Circumference
Between 68.5 and 69.5g (Size 5)
4
Sphericity
Average measured variation: maximum 1.5%. We measure the football's sphericity at 16 different points and examine the recorded discrepancies. If the discrepancy is greater than 1.5% (FIFA PRO Standard), our engineers are tasked with improving the sphericity to ensure a consistent bounce.
5
Maximum pressure loss
We inflate the football to the recommended pressure (meaning 0.8 bar). 72 hours later, the football 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 football to lose pressure after a few days.
6
Water absorption
We simulate rainy playing conditions in a lab, leaving the football to sit in 2 cm of water on pivoting support whilst subjecting it to 250 compressions. By the end of the test, the football ball must not have absorbed more than 15% of its weight, meaning approx. 60 g for this F100 in size 5.
7
Bounce
Between 135 and 155cm with a maximum difference of 10cm between the ball's highest and lowest bounce. Each football ball is dropped 10 times on a steel plate from a height of 2 metres.
8
Shape and pressure retention
The most stringent test we put this football 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
