FROM BELLY ARMOR:
The Belly Band is for expecting mothers who prefer less snugness around their belly and a looser fit. The pleated design makes it easy to adjust coverage vertically and discreetly cover unzipped pants as your belly grows. The Belly Band is lined with RadiaShield® Fabric, a highly conductive silver textile with the same shielding properties as a 1/4-inch thick sheet of aluminum. It shields by neutralizing incoming electromagnetic waves, canceling out the ambient radiation and reducing your exposure.
Instructions: Wear under or over clothes throughout your pregnancy, with larger side fully covering your belly.
