We made the ultra-soft, sponge-like cover of our UltraPlay volleyballs even softer and added an official spiral volleyball design, allowing even the youngest players to find success and feel like the MVP. The heavy-duty rubber is not only extremely durable, it is friendly on arms to take the sting out of incoming bumps and sets. Designed for comfort soft cloth and provide confidence-inspiring play and happy players. Red, white, and blue spiral panels allow for easy tracking. Official size and weight.
