Light, comfortable undergarments you can wear alone or over your regular underwear to shield yourself from power line and computer electrical fields, and microwave, radar, and TV radiation. This silver plated, stretchable, washable nylon mesh fabric is electrically conductive. It reflects radiation. Plus you won’t get those static shocks as you used to in dry weather and your clothes won’t cling to you! Fabric provides 40-50 dB from at least 30 MHz to 3 GHz. Surround what you want to protect!
