Product benefits
  1. Durability
    Panel stitching is on the inside, subsequently less subject to wearing
  2. ball touch
    We have placed foam panels on the outer cover for your playing comfort.
  3. Lasting air retention
    Guaranteed to keep ball pressure for longer thanks to Butyl et Latex bladder.
  4. Bounce
    Consistent rebound thanks to the quality of bladder and outer cover
  5. Precision
    Bladder wrapped in a thread to maintain its shape and ensure greater accuracy
Product feature
  1. Design
    Our design team watched football players in action on the pitch to develop this Hybrid ball. This ball is a hybrid as it combines the comfort of machine stitching with the durability of hand stitching. We also used a bladder with winded thread (2 km of threads are wrapped around the bladder) to ensure durable inflation and better sphericity.
  2. Weight
    Between 370 and 390 g (Size 4)
  3. Circumference
    Between 63.5 and 64.5 cm (Size 4)
  4. Sphericity
    Average measured variation: maximum 1.5%. We measure the football's sphericity at 16 different points and examine the 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.
  5. 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.
  6. 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. By the end of the test, the ball must not have absorbed more than 15% of its weight, meaning approx. 60 g for this F100 in size 4.
  7. Bounce
    Between 135 and 155cm with a maximum difference of 10cm between the ball's highest and lowest bounce. Each ball is dropped 10 times on a steel plate from a height of 2 metres.
  8. Shape and pressure retention
    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 general state: 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.
Product testing
  1. Composition
    Outcover : 100.0% Polyurethane (PU) Bladder : 100.0% Rubber - Butadiene Rubber (BR) Foam : 100.0% Ethylene Vinyl Acetate (EVA) Backing : 100.0% Polyester (PES)
  2. Product information
    For this F500 hybrid football, our design teams chose to use an foam inner cover for extra comfort during play and invisible stitching for greater durability.
  3. Lab tested
    Compliant with international football federations' most stringent standards.
