So what can you do to protect yourself from this nosy behavior? If you're familiar with the concept of the Faraday cage, you probably have an idea. A Faraday cage is a device made of a conductive material, such as metal, that blocks things like electromagnetic waves and signals. The CHBL Jammer Coat is basically a wearable Faraday cage for your body.
It looks a lot like something Gandalf might wear. Constructed from metallic fabrics, the Jammer Coat effectively blocks radio waves and signals from tracking devices. It comes with multiple pockets for your tablets and phones, keeping them safe and invisible from electronic spying.
The cloak is also meant to hide your body shape by creating an "illusion of strange multiple body parts, which hides and frees the individual physicality."
