F550 FOOTBALL HYBRID BALL SIZE 5 - RED
Panel stitching is on the inside, subsequently less subject to wearing.
Lasting air retention
Guaranteed to keep ball pressure for longer thanks to its Butyl / latex bladder.
Bladder wrapped in a thread to maintain its shape and ensure greater accuracy.
Consistent rebound thanks to the quality of bladder and outer cover.
Extra feel thanks to 1.4 mm polyurethane outer cover.
Designed with 24 panels for a more stable trajectory.
|Description||Our design teams made the F550 ball with a thicker outer material to increase the ball's lifespan. Additionally, the 24-panel design improves stability.|
|BALL TYPE||Hybrid ball|
|BALL SIZE||Size 5|
|AGE||Over 12 years and adults|
|LEVEL OF PRACTICE||Advanced|
|TYPE OF PRACTICE||Game|
|Size||Circumference: 68.5 - 69.5 cm|
|Stable trajectory||We know that a stable trajectory is very important, particularly for long games or when playing as a goalkeeper. We've changed the construction of the outer cover to improve stability. Traditionally designed using 32 panels, we've designed the F550 using 24 identical panels. This improves the stability of the ball and makes it more comfortable to play with.|
|Weight||Between 420 and 445 gm|
|Sphericity||Average measured variation: maximum 1.5%. We measure the football's sphericity at 16 different points and examine the recorded discrepancies. If the difference is greater than 1.5% (FIFA Pro Standard), our engineers are tasked with improving the sphericity to guarantee consistent bounce.|
|Minimal 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 F550 in size 5.|
|Bounce||Between 135 and 155 cm with a maximum difference of 10 cm between the ball's highest and lowest bounce. Each ball is dropped 10 times on a steel plate from a height of 2 metres.|
|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:
|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.|
|Warranty||2 years warranty on the bladder|
|Storage advice||After use, store your ball in a dry and ventilated place.|
|Country Of Origin||China, Pakistan|
