We developed this F500 hybrid ball for footballers that play in clubs and need a comfortable and durable ball.. For this F500 hybrid football, our design teams chose to use a foam inner cover for extra comfort during play and invisible stitching for greater durability.

| Design | 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 stitching 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. |
| Weight | Between 420 and 445g (Size 5) |
| Circumference | Between 68.5 and 69.5g (Size 5) |
| 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. |
| Maximum pressure loss | 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. |
| 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. By the end of the test, the ball must not have absorbed more than 15% of its weight, or approx. 60 g for this F500 in size 5. |
| Bounce | 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 2 meters in height |
| Shape and pressure retention | 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 |
