Frequently asked questions
About shielding, sizing, care and ordering.
Shielding and the science
What does silver-fiber shielding actually do?
Our fabric knits 99.9% pure silver thread into the base fiber. Silver is highly conductive, so it reflects and redirects a portion of RF energy before it reaches your body.
Does this block all EMF exposure?
No single garment eliminates exposure entirely. Our apparel is designed to reduce exposure from nearby devices, wiring and wireless signals as part of a broader approach.
Is the shielding tested?
Yes. Each fabric batch is measured for shielding effectiveness before it becomes a garment. Details are on The Fabric page.
