Portable systems require minimal installation and offer ultimate convenience. These systems generally feature a base that can be filled with sand or water to stabilize them and include wheels for portability. Although they are not as sturdy as in-ground or wall-mounted hoops, portables are simple to set up and can often be folded for convenient storage.
