BKT Ligue 2 Official Replica Ball 2023 Size 5

As a result of the consultation launched in March 2021, the Board of Directors of the LFP has designated Kipsta, Decathlon group's football brand, as the new official supplier of the LFP.Kipsta premium footballs, designed in France, have been awarded the FIFA Quality Pro label and undergo quality tests at various stages of production.With the official balls of the Uber Eats Ligue 1 and BKT Ligue 2, Kipsta wishes to demonstrate its know-how at the highest level of competition.

This ball, just like the whole of our range, is 100% designed in France, and has been rigorously tested by a combination of lab and field tests. So it meets the strictest standards and requirements, as well as complying with a whole range of additional tests, specifically developed by Decathlon.Apart from normative tests, our Kipsta Certification Unit carries out additional tests, that enable us to design, but also objectively compare our products.

Our balls are produced by our industrial partners in Asia (Pakistan and China for this ball).Pakistan is known and recognised as the football ball capital of the world.Over 50 years of high-quality craftsmanship.

The Kipsta certification unit is a team made up of qualified field trial engineers, renowned for: establishing specific protocols and tests relating to how the products will be used.Recruitment of qualified testers with a level suitable to evaluate products' functions.Objective analysis of results, using statistical tools.These tests cover general aspects, such as durability, durable inflation, and functions that reflect the ball's technical aspects.

To design our balls, we have a dedicated team, as well as a laboratory based in France. The Ball team in France is made up of product engineers, component engineers and test engineers, which means we are able to master the entire ball design process, from components to technical validation.

At Decathlon we've been testing our balls for over 15 years in order to validate our products during the design, industrialisation and post-production phases. A laboratory 100% dedicated to ball tests was even created in 2018 at the Kipstadium site in France.More than a dozen tests are carried out on our balls. First of all, there are the tests required by FIFA, as well as other, additional tests, created by the engineers within our laboratory.

With 40 years' experience as a designer, Decathlon bases its product development on desirability and accessibility for all, consequently implying a notion of universality in their design (age, gender and nationality).The group's, and therefore Kipsta's, aesthetic line is a balance between our convictions (simple, technical and clever products) and our sober, universal and modern artistic direction.

The DNA worked into this ball (i.e. the formal basis on which a graphic design is juxtaposed) combines technical features and balance.The spatial apprehension and the visual effects linked to the ball during its movements are worked on so as not to cause any visual discomfort to the players, thus supporting the design choice.

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.

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

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

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.

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.

Here's how we test 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.At the end of the test, the ball must have absorbed no more than 10% of its weight (FIFA Basic certification).

Here's the bounce test:The ball is dropped onto a steel plate 10 times from a height of 2 metres.The bounce height must be between 125 and 155 cm with a maximum difference of 10 cm between the ball's highest and lowest bounce.

The most stringent test we put this ball through is the shooting machine test.The ball must resist 2,500 shoots against a concrete slope 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: It must not have increased more than 1.5 cm.- the sphericity: it must not have varied by over 1.8%- the pressure: loss of pressure must not exceed 12.5%.

We value your feedback and use it to continuously improve our products.A huge thank you in advance for sharing your feedback with us.
