EIT CONSTRUCTION: 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.

LONGER LASTING: A key benefit of EIT is longer life versus traditional balls. This is measured by the compression or firmness of the ball. Even after 100 hits. EIT baseballs experienced only a 35% drop in compression whereas traditional baseballs lost 53% of their original compression. The benefit? Performance on the field is maintained much longer with EIT.

ALL CONDITION PERFORMANCE: Another major benefit with EIT is consistent performance under a wide variety of conditions. Humidity plays a major role. Extensive testing has proven that baseballs can gain weight and lose performance depending on humidity levels. At 80% relative humidity, a traditional baseball can gain over 1/3 ounce in weight and drop below specified C. O. R. levels.

MOISTURE REPELLENT: Lastly, Extra Innings Technology protects against the most obvious environmental enemy of baseballs … water. EIT polymer layer restist water from being absorbed into the ball’s windings. The result is a longer lasting, better performing ball when playing in wet conditions or extended life in the practice bucket.
