Abstract
A sports ball comprises a bladder and a contouring layer surrounding the bladder. The contouring layer includes at least one panel defining a repeating pattern of perforations configured to lower a Poisson's ratio of the contouring layer. Each of said perforations defines a reentrant shape and a constant cross-sectional width in a radial direction of the ball.
