Composite / Synthetic Leather – these basketballs are covered with artificial or synthetic leather material that has the feel of leather, as it has been designed that way, but much cheaper to produce and manufacture. Since it is synthetic, the material has a uniform feel which is why it does not need to be broken-in as it already has that soft feel even when new.
It’s just a recommendation and there is way more information about basketball sizes as every coach and sport doctors has unique positions. Production material. In many respects quality of a basketball, depends on from what material it is made. The most widespread materials which are used by production of basketballs are: 1. Rubber

For many years, leather was the material of choice for basketball coverings, however, in the late 1990s, synthetic composite materials were put forth and have rapidly gained acceptance in most leagues, although the NBA's game balls still use real leather (outside of a brief experiment with a microfiber ball in 2006 that was not well received).
A layer of thread insulates the area between the outside ball cover and the inner bladder, adding a layer of protection that helps the ball retain its spherical shape. Nylon and polyester are typically used to create a symmetrical layer of winding over the bladder.
You'll need a ball to play the game. Today, basketballs are made with synthetic materials such as rubber, polyester, and nylon in combination with leather. In the NBA, the pressure of the ball must be between 7.5 and 8.5 pounds per square inch. The size of the ball measures 29.5 inches around in circumference.
The basketball’s material is another feature to take into consideration, although material may largely depend on league requirements if you’re playing competitively. There are three basic types of material: leather, synthetic (also known as composite) and rubber. When the pros play, they’re using leather basketballs.
