With GOTS certified organic cotton and knitted-in silver yarn, this shirt protects against electromagnetic radiation from transmission towers (5G, 4G), WLAN, DECT phones, baby monitors, Bluetooth, etc. Ideal for everyday use as underwear but also as a T-shirt.
Very comfortable to wear - no difference in wearing comfort to normal underwear.
Shielding: 99.5% effective at 5G (21dB at 3.5GHz)
Colour: as the black fabric is no longer manufactured, we are replacing black with dark blue – certain sizes have already been switched to dark blue. This is indicated in the size selection. The fabric is the same; only the colour is different.
The measuring was carried out by Prof. Dipl.-Ing. Peter Pauli, Professor for High Frequency, Microwave and Radar Technology at the University of Munich.
