Shielding Cap Black Jersey

Properties

Comfortable thin cap made of Black-Jersey fabric with 40dB shielding attenuation. Black-Jersey is a dense cotton fabric with high silver content. Currently YShield’s best and most durable fabric for shielding clothing. The fabric is from Germany and has an unusually high shielding attenuation for such a high cotton content.

Our textile products are hygienic products, that can’t be returned after being used. You can try the cap on to see if it fits, but not wear it for a longer period of time – this will be visible on the fabric immediately. If the product shows traces of wear or traces caused from trying it on, we will not accept the return.

Laboratory & expert report of shielding attenuation up to 40 GHz

YShield invested in their own professional EMV laboratory years ago. They not only use it to create their laboratory screening reports but also to check each batch daily. Additionally, they have all their products checked by an independent, well-respected expert. Double checked for twice the safety.

Ready for 5G

Some companies offer “special” 5G-products. This products shields all 5G-frequencies, even without advertising this! Find two gray bars in all shielding diagrams with the 5G frequency spectrums FR1 (600 MHz – 6GHz) and FR2 (24 GHz – 40 GHz).
