SLVR777: Medical-Grade 50 GHz RF Shielding Silver Fiber Fabric

Quick Answer

SLVR777 is a precision-engineered textile developed by SLVR Wear, featuring 35% pure silver fiber woven directly into its structure to provide inherent RF shielding. This fabric offers up to 99.91% RF attenuation, independently lab tested to 50 GHz, which covers the full deployed and emerging 5G spectrum. Unlike other materials, SLVR777's shielding is an integral part of the textile, ensuring durability and consistent performance. The silver fiber in SLVR777 is OEKO-TEX® Certified, meeting high standards for human ecological safety.

SLVR777 – Two Years to Build the World’s First 50 GHz Medical Scrub Fabric

Most RF protection fabrics are afterthoughts a coating sprayed onto an existing textile, or a thin silver layer laminated between two sheets of synthetic fiber. They look good in product photos. They fail in the wash. We spent two years developing something different. SLVR777 is a precision-engineered textile co-developed with our exclusive manufacturing partner, in which 35% pure silver fiber is woven thread-by-thread into the fabric structure itself. The shielding isn’t applied. It’s the textile. This is the fabric behind every Silver Scrubs® product in our line.

Why 50 GHz Matters

5G networks operate across a wide spectrum. Sub-6 GHz frequencies cover most current 5G deployment. Millimeter-wave 5G (mmWave) operates from roughly 24 GHz to 47 GHz, with planned future expansion into higher bands. Many shielding fabrics test only up to 20 GHz or 40 GHz, leaving the higher mmWave frequencies untested. SLVR777 is verified to 50 GHz – covering the full deployed and emerging 5G spectrum, plus traditional Wi-Fi, Bluetooth, and cellular bands.

Frequently Asked Questions
