The Official Tournament Set of the Spikeball Roundnet Association. The Pro Kit is for any serious player whose game has outgrown the original Spikeball Set. A sturdier body design keeps the set stable and net taught during the harshest of plays. A new material and added texture on the Pro Balls help players add topspin on their kills and back spin on their drop shots. The Spikeball Pro Set includes: Spikeball Pro net, 2 Spikeball Pro balls, Portable ball pump and gauge, and Backpack.
