The Mag-Volt should not be put on top of the fabric ball band. Things do tend to get a bit less organized when wearing the Innerwear with ball band and Mag-Volt at the same time, however, the metal generally does stay in contact with the skin for the salt bridge circuit that Whaim mentions. I tend to wear the strapless Innerwear with the Mag-Volt acting as the baseband. Two Mag-Volts in tandem replicated the width and function of the ball band very well.
