Abstract
A game ball having a high end synthetic leather cover formed from a non-woven fiber mat impregnated with polyurethane. In one embodiment, the game ball is a football and the fibers in the backing of the cover material have a denier of about 0.1 or less. In another embodiment, the game ball cover has a dual layer coating to impart to the cover good pebble retention. The first layer has a Shore A hardness of at least about 65, and the second layer surrounding the first layer has a Shore A hardness lower than the hardness of the first layer. The game ball, which can be formed to meet association specifications, has properties of softness and durability comparable to those of a genuine full grain leather game ball.
