Bola Sepak Football Thermobonded Ball FIFA Pro BS9 Size 5 Yellow

8610677 We created this ball for matches and training for competitive soccer. Our design teams created the BS9 ball with a 12-panel outer cover to ensure perfect sphericity and greater stability. Durability Laminated bladder with thermobonded construction (no stitching). Lasting air retention Guaranteed to keep ball pressure for longer thanks to Butyl/Latex bladder. Stable flight Thermobonded ball with textured component for optimum accuracy. Bounce Stable trajectory thanks to its thermobonded 12-panel construction. Ball touch 5 mm foam outer cover for excellent comfort. When creating this beach soccer ball, our designers used thermobonding technology (seamless) to guarantee perfect sphericity and more precise shots. In addition, this technology ensures better waterproofing. Exclusive construction We know that, in matches, the little details make all the difference. For this BS9 ball, we wanted to really focus on having a stable trajectory so that players and keepers could better read the ball in the air. To do this, we tested different types of outer panelling and chose the one which showed the best results. Weight Between 430 and 445g in size 5 Circumference Between 68.5 and 69.5 cm. Sphericity Average measured variation: maximum 1.5%. We measure the football #39;s sphericity at 4500 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. 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.
