We created this ball for matches and training for competitive beach soccer.

Our design teams created the BS9 ball with a 12-panel outer cover to ensure perfect sphericity and greater stability.

Outer shell: 100.0% Polyurethane; Bladder: 100.0% Latex Rubber; Inside shell - Main lining: 100.0% Polyester

BENEFITS

Durability

Laminated bladder with thermobonded construction (no stitching).

Lasting air retention

Guaranteed to keep ball pressure for longer thanks to Butyl/Latex bladder.

Bounce

Stable trajectory thanks to its thermobonded 12-panel construction.

ball touch

5 mm foam outer cover for excellent comfort.

TECHNICAL INFORMATIONS

Design

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. Finally, to optimise the sphericity of this ball, we chose a laminated bladder (fabric strip bonded to the latex bladder) to guarantee even more robust inflation.

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. The 12-panel design is a Kipsta exclusive.

Quality testing

We conducted numerous lab tests on the ball in order to provide the excellent accuracy that beach soccer players require while competing. Each test is outlined below.

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'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.

Water absorption

We simulate rainy playing conditions in a lab by leaving the ball to sit in 2cm of water on a pivoting support whilst subjecting it to 250 compressions
At the end of the test, the ball can not have absorbed more than 10% of its weight, or 40 grams for the BS9. This is one of the advantages of the thermobonded process; water absorption is limited in comparison to other processes (machine-stitched for example)

Bounce

Between 135 and 155 cm with a maximum difference of 10 cm between the ball's highest and lowest bounce. Each ball is dropped 10 times on a steel plate from a height of 2 metres.

Shape and pressure retention

The most demanding test that this ball is subjected to is the machine shot test.
Resists up to 2500 shots against an elevated flat surface at 50 km/h at 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: it must not have varied by over 1.5%
- the pressure: loss of pressure must not exceed 0.1 bar.
