The thermo bonding method means that the panels are thermally glued and bonded by heat. There are no stitches, so the TB balls take up less water and keeps the original weight better when playing on a wet surface. BRILLANT SUPER TB has the characteristics that distinguish a classic AZCO ball and is suitable for matches at the absolute highest level. The materials are carefully selected and have exactly the qualities that give the best playability and durability .The outer material of the ball consists of synthetic leather with a light surface structure that minimizes air resistance. Under the synthetic leather hides the AZCO natural latex Zero-Wing bladder with a built-in balance point in the opposite end of the valve hole. On the outside of the bladder is a lining made of a 4 mm. thick and exclusive foam material. The outer material and the underlying foam give the ball a softer, lighter and a more comfortable touch. Despite the fact that the ball feels lighter, the weight is the same as a traditional football.
