Rawlings Incredi-Ball SoftStitch Training Softballs were designed to be a safer alternative to traditional practice balls. The Incredi-Ball Training Softballs are significantly lighter than traditional practice balls and wrapped in a soft to the touch, nylon fabric cover that won’t mark floors. Safe for all ages and suitable for use indoors or outdoors, the Incredi-Ball is an excellent training ball for practice time away from the field!
