We publish the real numbers
Our silver mesh fabric was independently measured from 300 MHz to 20 GHz, the range that covers cell, Wi-Fi, Bluetooth, and sub-6 5G.
60.7–69.0 dB
Shielding effectiveness of the silver mesh material, measured under controlled conditions. A cap is not a sealed enclosure, and we don't claim it performs like one; results vary with frequency, fit, coverage, and distance from the source. Test data and method available on request.
