A sportsball, comprising:

• a ball cover having a valve hole provided thereon and comprises a plurality of panels, each having a predetermined shape, connected edge to edge to form a roundness shape;
• a bladder, which is disposed inside said ball cover, comprising a bladder ball, an exterior web layer integrally attached on a predetermined area of an outer surface of the bladder ball, and a valve stem which is mounted on said bladder ball and is outwardly extended to an exterior of said ball cover through said valve hole for air inflation, wherein said web layer comprises at least an elongated strengthened thread evenly wound around said outer surface of said bladder ball in such a manner that said strengthened thread is overlapped to form said web layer to entirely embrace said bladder ball for supporting said bladder ball and resisting a stress and impact force applied to said sportsball, wherein a gap is formed between each of said panels and said bladder after inflation;
• and
• a stress absorbing layer comprising a plurality of absorbing pads each having a flexibility ability, wherein said absorbing pads are fittedly attached to said panels respectively, wherein each of said absorbing pads has a thickness to fill up said gap defined between said respective panel and said bladder so as to increase a contact area between said ball cover and said bladder and reinforce said roundness shape of said sportsball.
