Baden s All Weather Baseball - Designed and tested in the Pacific Northwest - is the original all-weather practice ball. With a waterproof core made of rubber, cork and proprietary bonding agents, the ball remains playable even when wet and returns to its original weight after just 24 hours of drying time. Blue stitching allows for easy identification and helps coaches, players and equipment managers avoid ruining standard wound balls in wet conditions. The all-weather ball has been used by high school and college programs across the country for years, providing the perfect protection in any climate.
