This is the ultimate tape to add maximum grip on a hula hoop. It is installed on the inner surface of the tube and, as the name suggests, is nearly invisible and does not affect the appearance of the hula hoop. That said, many don’t appreciate the strength of the grip and compare this tape to sandpaper. It is nevertheless very appreciated by others.

It is not strictly speaking a grip tape (it is installed as protection over the other tapes), but it also adds excellent grip to the hula hoop (more than gaffer tape, but less intense than 3M tape). It is therefore not necessary in this case to add grip tape and, of course, it is not useful to install other grip tape underneath, except for aesthetic reasons.
For hula hoops that aren’t finished with tape, like colored polypros, there are other ways to add grip. You can sand the inside of the hula hoop with sandpaper to roughen it or apply wax which also increases the grip. The latter solution, however, requires repeating the operation after each use. You should also know that if you choose to sand the inside of a hula hoop, it will be more problematic to apply tape thereafter, since it will adhere less easily.
