Best Answer

Nearly all basketballs have an inflatable inner rubber bladder inside, generally wrapped in layers of fiber and then covered with a tacky surface made either from leather (traditional), rubber, or a synthetic composite. As in most inflatable balls, there is a small needle valve opening to allow the pressure to be increased or decreased.

Precise specifications no doubt vary slightly from league to league; NBA, WNBA, Olympic, International, Under 20 etc., etc. Best consult specific league websites for most current details.
