The soccer ball V2.0

FIFA Approved Standard: max. 1.5% difference The adidas +Teamgeist: max. 1.0% difference

Water absorption test

A wet and heavy ball behaves quite differently from a dry one. It flies through the air more slowly, has a low bounce and is more difficult to curl. adidas’ patented Thermal Bonding technology makes a football virtually waterproof. As a result the new Match Ball shows completely homogenous performance characteristics when playing in dry or wet conditions.

For the water absorption test, the ball is pressed and rotated in a container of water 250 times, after which the ball will be weighed. The water will also be weighed before and after the water uptake test.

FIFA Approved Standard: Water absorption: no more than 10% weight increase The adidas +Teamgeist: Water absorption: no more than 0,1 % weight increase

Perfect weight test (420 – 445 grams)

Each professional game is played with a number of balls. These different balls all need to perform the same. Consistency in weight is crucial. If the ball is too light or too heavy, it might move unexpectedly in flight.

FIFA Approved Standard: Weight between 420 and 445 grams The adidas +Teamgeist: Weight between 441 and 444 grams
