The ball stitching is inside, making it invisible and more durable.
Lasting air retention
The butyl and latex bladder retains pressure for longer.
Lighter football (350 g).
Hybrid ball for better sphericity, guaranteeing high precision.
Technical components provide a consistent bounce.

- Our design team created this hybrid ball after observing football players in action on the pitch. This ball is a hybrid, meaning that in its design, we combined the comfort of machine stitching with the durability of hand stitching. We also used a bladder with winded thread (2 km of threads wrapped around the bladder) to ensure durable inflation and better sphericity.
- This ball is so-called "Light" because it is on average 15% lighter than a "classic" size 5 football. For a young football player, this provides 2 major advantages. Firstly, it's more pleasant to kick or do headers with. Secondly, it's easier to lift the ball as well as to make longer passes or shoot at goal targets.
- Between 68.5 and 69.5 cm.
- We measure the football's sphericity at 16 different points, and then examine any recorded discrepancies. If the discrepancy is greater than 1.5% (FIFA PRO Standard), our engineers are tasked with improving the sphericity to ensure a consistent bounce.
- 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.
- We simulate rainy playing conditions in a lab, leaving the ball to sit in 2 cm of water on a pivoting support while subjecting it to 250 compressions. By the end of the test, the ball must not have absorbed more than 15% of its weight, which in the case of this F100 Light Size 5 is approx. 50 g.
- Between 125 and 155 cm with a maximum difference of 10 cm between the ball's highest and lowest bounce. Each ball is dropped 10 times onto a steel plate from a height of 2 meters.
- The most demanding test that this ball is subjected to is the machine shot test. Withstands up to 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 overall condition: stitching must withstand this test - the circumference: must not have increased by more than 1.5 cm. - the sphericity: must not have varied by more than 1.5%. - the air pressure: loss of pressure must not exceed 0.1 bar.
