摘要:
A ball comprising an interior layer; an intermediate layer having a plurality of spacer panels extending radially outwardly from the interior layer, the panels each having interior edge located adjacent to the interior layer and an exterior edge and lateral side edges therebetween coupled to lateral side edges of adjacent panels in a waffle-like configuration to form a plurality of recesses extending downwardly from the exterior edges to thereby form a grid pattern of recesses with an exterior surface formed from the free exterior edges; and an exterior layer adjacent to the exterior surface of the intermediate layer for entrapping pockets of air within the recesses.
