Kipsta Adult Size 5 Fifa Hybrid Football, White

We have designed the FIFA-approved F500 hybrid ball, which pairs comfort with durability, for your training sessions and competitions.

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 410 g and 450 g (size 5) and complies with official FIFA standards.
FIFA Basic approved.

HOW BIG IS IT? WHAT'S THE CIRCUMFERENCE?

This ball measures between 68.0 cm and 70.0 cm and complies with official FIFA standards.
FIFA Basic approved.

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.
