A non-wound golf ball, comprising a central core, a cover having a thickness of at least about 30 mils and comprising a member selected from the group consisting of ionomers, acrylic acid, methacrylic acid and polyethylene surrounding the core, and a moisture barrier surrounding the core and being located between the cover and the core. The moisture barrier has a lower water vapor transmission rate than the cover and an average thickness substantially less than the cover thickness. The moisture barrier has a water vapor transmission rate which is sufficiently low to reduce the loss of coefficient of restitution of the golf ball by at least 5% if the ball is stored at 100.degree. F. and 70% relative humidity for six weeks as compared to the loss in coefficient of restitution of a golf ball which does not include the moisture barrier, has the same type of core and cover, and is stored under substantially identical conditions.
