Brando is now offering the Black Hole phone bag, a pouch for your phone with two pockets. One of the pockets is ‘normal’ and just carries your phone, but the other pocket features a cell blocking material which essentially turns it into a Faraday cage. Slipping your precious mobile into this special pocket blocks all incoming and outgoing cell signals. It seems like a strange solution when simply turning off the phone offers the same functionality without the $12 price tag, but somehow we suspect that that may not be enough for the ultra-paranoid among us.
