STIGA Outdoor Table Tennis Balls are the perfect accessory for a recreational outdoor game. These balls are designed to play better in the unique elements that outdoor play brings. They are wind resistant, allowing the ball to fly as true as possible, and water resistant. They are also incredibly durable, and able to stand up to the damage outdoor play can bring. STIGA outdoor balls are the perfect match for a STIGA Flow Outdoor Racket and STIGA Baja and Coronado outdoor tables.
