Hybrid Football F500 Size 4 - White

Made for
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.

Advantage
DurabilityPanel stitching is on the inside, subsequently less subject to wearing
ball touchWe have placed foam panels on the outer cover for your playing comfort.
Lasting air retentionGuaranteed to keep ball pressure for longer thanks to Butyl et Latex bladder.
BounceConsistent rebound thanks to the quality of bladder and outer cover
PrecisionBladder wrapped in a thread to maintain its shape and ensure greater accuracy

Technical Information

1
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 winded thread (2 km of threads are wrapped around the bladder) to ensure durable inflation and better sphericity.
2
Weight
Between 370 and 390 g (Size 4)
3
Circumference
Between 63.5 and 64.5 cm (Size 4)
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 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.
6
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, meaning approx. 60 g for this F100 in size 4.
7
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 a height of 2 metres.
8
Shape and pressure retention
The most demanding test that this ball is subjected to is the machine shot 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: must not have increased by more than 1.5 cm. - the sphericity: it must not have varied by over 1.5% - the pressure: loss of pressure must not exceed 0.1 bar.
