Baseball - Rawlings Official Cal Ripken Baseball Dozen

Ripken Tournament Grade Baseball. Made with a full grain leather cover for added durability. Cushioned cork center. Rawlings raised seam construction for improved grip.

Extra Innings Technology - EIT Baseballs contain a patented, thin, polymer layer just under the cover which resists the damaging effects of moisture (liquid and vapor) on not only durability but also performance. This layer also plays a key role in maintaining the ball's firmness.

Extensive testing has shown that EIT baseballs are hands down, superior to traditional balls. The bottom line: EIT baseballs last longer and perform better in a wide variety of conditions.
