With 40 dB attenuation measured across 600 MHz to 40 GHz, it provides effective protection against high-frequency electromagnetic fields including all 5G frequency bands (FR1: 600 MHz–6 GHz and FR2: 24–40 GHz).\u003c\/p\u003e\n\u003cp\u003eBlack-Jersey is notable for achieving unusually high shielding attenuation for a fabric with such a high cotton content, combining a natural feel with strong electromagnetic shielding performance.
