A softball has a high end synthetic leather stitched cover formed from a low density non-woven fiber mat impregnated with polyurethane. The softball, which can be formed to meet association specifications, has a circumference of 11 or 12 inches and a cover to core weight ratio significantly less than 0.1, typically in the range of 0.08-0.16, while meeting durability requirements. The cover preferably has a thickness of 0.045-0.065 inches. Because a greater weight concentration is in the core of the ball, the ball has improved playability characteristics over conventional balls having heavier synthetic leather covers, while exhibiting a sound comparable to that of a leather covered softball when struck with a bat.
