Shieldtech has been tested for safety in accredited labs and is fully certified. Shieldtech is also antibacterial, sweat-absorbent, and thermodynamic so it neutralizes odor-causing microbes and helps keep you cool when it's hotter temperatures, and warm when it's colder.
No. Any small amount of radiation that may leak into or through the pouch has already been vastly weakened. Additionally, fabric polarization manifests a repel effect which further shields from direct radiation exposure.
Radiation exposure from the back and side don't penetrate the body deep enough to reach your reproductive organs. Paradoxically, due to polarization, the more radiation Shieldtech is exposed to, the stronger the fabric becomes. Shielding garments which cover too much of the body may desynchronize biofields.
