I have the Hydra 1955 - bought abdominal and back belt, since this hardly restricts the freedom of movement and is simple and invisible to wear under clothing. That's what I expected from this belt too. My ärtztlich ordered back support gives the back, of course, more support, but is not so convenient. In einme acute disc herniation of Hydra 1955 - abdominal and back belt because of the small supporting force certainly not the right choice However, as Figure shapers or moderate back relief is this inexpensive belt helpful. Tip: Fix the belt once the Velcro straps and let the removing or closed. From the bottom board with the legs and belt pull up to the back. This saves the fumbling when fastening the Velcro fasteners.
