It consists of 6 layers of composite material, and the out cover is made up of 6 layers of propeller-shaped polyurethane leather.
The texture on the skin is used to direct the airflow and maintain the stability of the ball in the air.
In order to make the ball smoother, the ball uses thermal bonding technology to make the air flow more smoothly in the groove between the spheres.
The second layer is a closed-cell foamed plastic that prevents moisture from spreading in it.
The third layer is the first layer of fiber reinforced layer, which helps the football to rebound back to its original shape after being impacted.
The fourth layer is an open-cell foamed plastic layer that is very soft and has good elasticity.
The fifth layer is sandwiched between the open-cell foamed plastic layer and the inner liner.
After the football is inflated, this layer is subjected to the maximum pressure.
The sixth floor is the inner tank, full of air.
