摘要
A sport ball includes a casing that includes a plurality of joined panels and defines a cavity. The casing includes at least a first panel having (a) a first layer positioned to form a portion of an exterior surface of the sport ball, (b) a second layer disposed adjacent to the first layer, and (c) a third layer disposed adjacent to the second layer. The first panel defines a first indentation and a second indentation spaced apart from the first indentation. The first indentation has a first depth and the second indentation has a second depth that is less than the first depth. The first depth is from 0.5 times to 4 times larger than the second depth. The sport ball also includes a bladder disposed within the cavity.
