At Vermont Sports, we pride ourselves on the quality of our ITF-approved kids tennis balls. Specifically designed for youth players to use, mini tennis balls are larger and lighter than senior balls, making them easier to hit and much more fun & enjoyable to play with. We have Stage 3 red mini tennis balls for players 8 years old and under, Stage 2 orange mini tennis balls for children aged 8 & 9, and Stage 1 green mini tennis balls for players aged 9 & 10. We also supply foam mini tennis balls that are designed to bounce significantly lower than standard tennis balls, ensuring young children can practice ground strokes at the correct height relative to their size.
