    Abstract: A portable net system for a racquet sport. The portable net has a first stanchion and a second stanchion. The first and second stanchions are configured to mate together forming a carrying case. The portable net includes a self-retracting net that resides within the first stanchion, and which unspools from the first stanchion according to a desired width of a court. The leading edge of the net clips or otherwise fastens to the second stanchion. Thus, as the first and second stanchions are separated, the net unspools forming a net for a racquet sport. Each of the first and second stanchions additionally includes a base that provides support for the portable net in a vertical orientation.
