Learning to kick a ball and get it off the ground is not as easy as it looks. That #39;s why we created this ball, which is 15% lighter than traditional balls.

Lasting air retention Guaranteed to retain its pressure for longer thanks to its butyl bladder. Bounce Your ball complies with international requirements in terms of bounce. Stable flight The classic 32-panel design with invisible seams. Lighter than a regular ball This ball is considered light because it is about 15% lighter than a regular size 5 football. What difference does that make? Thanks to its weight, young football players can kick or head the ball more comfortably. It #39;s also easier to aim and execute long passes. How big is it? What #39;s the circumference? The size of this ball is between 63.5cm and 64.5cm (size 4), and between 68.0cm and 70.0cm (size 5). Maximum pressure loss test: here #39;s what we do... Here #39;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. Here #39;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 125 and 155 cm with a maximum difference of 10 cm between the ball #39;s highest and lowest bounce.
