You are feeling like a spy?
Someone watching your coordinates via mobile phone? You don't want someone to call you now? Yes, you are a spy and you need a secret pocket to shild your phone. Of course you could buy a special protective pouch, but it may arouse suspicion...

Make one of your pockets a Faraday cage using the carbon fiber tape (and now on Amazon). This is very simple and fast. See how easy it is.

Step 1: Now To...

Gently unpick the lining of your jacket.

Turn the pocket inside out.

Wrap pocket with Iron-on no-sew hem tape and carbon tape.

Gently iron it.

Step 2: Say Nobody

Sew lining. Faraday secret pocket is ready.

In the event of danger place a phone in the secret pocket. Your phone will disappear from the telephone network. No one can call you. Nobody will be able to determine your location or overhear you. No one will know that you are using the Faraday cage. Because it is a soft carbon tape, no one will distinguish it from a normal fabric, no one uncover you. Сause you're a spy.
