Description
Durability: The panels' stitching is on the inside so that it won't wear out as fast. Lasting air retention: Guaranteed to retain its pressure for longer thanks to its butyl bladder. Stable flight: The classic 32-panel design with invisible seams. Bounce: Your ball complies with international requirements in terms of bounce Ball touch: We have placed foam panels on the outer cover for your playing comfort. The story behind this ball: Our design team created this hybrid ball after observing football players in action on the pitch. This ball is a hybrid because its design combines the comfort of a machine-stitched ball with the durability of a hand-sewn one. We also used a bladder with a special design (2 km of thread is wrapped around the bladder) to ensure lasting inflation and better sphericity. Too light? Too heavy? The weight is standardised...: This ball weighs between 290 g and 335 g (size 3) and complies with official FIFA standards. How big is it? What's the circumference?: This ball measures between 58.0 cm and 60.0 cm (size 3) and complies with official FIFA standards. A "round" ball?: Here's how we test sphericity: Average measured variation: 1.8% max (FIFA Basic certification). We measure the football's sphericity at 4500 different points and then examine any differences. If the discrepancy is greater than 1.8 % (FIFA Basic Standard), our engineers are tasked with improving the sphericity to ensure a consistent bounce. Maximum pressure loss test: here's what we do...: Here's how we test pressure loss: We inflate the ball to the recommended pressure (meaning 0.8 bar). 72 hours later, the ball must not have lost more than 15% of its pressure, meaning approx. 0.1 bar (FIFA Basic certification). 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've also tested how much water the ball absorbs...: Here's how we test 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. At the end of the test, the ball must have absorbed no more than 15% of its weight (FIFA certification). It's all about the bounce: Here's the bounce test: The ball is dropped onto a steel plate 10 times from a height of 2 metres. The bounce height must be between 115 and 155 cm with a maximum difference of 10 cm between the ball's highest and lowest bounce. Not even a scratch!: The most stringent test we put this ball through is the shooting machine test. The ball must withstand 2500 shots against an inclined concrete surface at 50 km/h from 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 1.8% the pressure: loss of pressure must not exceed 12.5%.
