The Spikeball Pro Set is the official tournament set of the Spikeball Roundnet Association. With a sturdy body design, the Spikeball Pro Set is more stable than the original and keeps the net taught during play. The Spikeball Pro balls feature new material and added texture to help players add topspin on the kills and backspin on their drop shots. For easy transport or storage, the Spikeball Pro Set even comes with a backpack. Have some fun with friends and family this summer with the Spikeball Pro Set.
