Don’t worry, we will get to the jacket- but first the story starts in 1836 in Victorian England. And it you weren’t there you didn’t miss anything. It included a grumpy-looking queen, bad weather, a lot of sexual repression, and rich people throwing buckets of human waste out of their windows. 

On the plus side it also had a bunch of scientists running around like kids on acid. One of them was Michael Faraday – Victorian England’s answer to David Blaine.

Over the last 190 years the Faraday cage has gone from a crazy Victorian scientist sitting inside an electrical storm, to critical black-ops architecture, to a wildly experimental jacket that looks like it’s emerged from a craft in Dune.

A Faraday cage at the US Bureau of Standards (now NIST) used to protect delicate measuring instruments from electromagnetic fields.

Now Michael was a showman. But instead of freezing himself in ice, or suspending himself in a glass box, his trick was making super abstract physics feel tangible. And his greatest stunt of all was standing inside an electrical storm. In front of a packed out theatre at the Royal Institution in Mayfair, Faraday lined a large wooden box with metal foil, hit it with discharges from high voltage electrical machines… then calmly stepped inside. Sparks crackled across the outside of the enclosure. Blue light crawled over the metal skin. Faraday meanwhile stood there in silence. Like the final boss. While the energy simply flowed around him.

It might have looked like he’d built his own supersized coffin – complete with all the necessary equipment to kill him – but it turned out Faraday understood equations as well as he understood spectacle. 

• Made from approx. 50% copper
• Blocks electromagnetic waves from 0.2GHz to 14GHz
• Eight-pocket defensive storage system with shielding flaps

By the time he stepped into his foil-lined cube, he’d already spent years dismantling older ideas of electricity.  

A Faraday cage isn’t a wall. It’s a detour. When an electromagnetic field hits a conductive enclosure, the free electrons inside it immediately start to flow, redistributing themselves across the surface until the field inside is cancelled out. Build the right shape from the right material, and electricity behaves like water flowing around a rock.

It’s one of the simplest demonstrations of how matter tells fields what they are allowed to do. The impact of Faraday’s experiment quickly escaped the lecture hall – because the Faraday cage didn’t just deflect static charge, but whole regions of the radio frequency and microwave spectrum.

The principle was applied in bunkers, test chambers and secure rooms. Then in spacecraft, data centres, radar installations and intelligence facilities, where even a stray spike of interference can crash systems or corrupt data. Today our Faraday Cage Jacket is a descendant not only of that wooden box, but everything that followed in its footsteps. It’s the same physics. Just shrunk. Softened. And wearable. And you can join the waiting list here.

We designed it from scratch, using the principles of clothing and electromagnetic infrastructure at the same time.

And this is what transforms it from a pure physics experiment, to an object that looks like it’s just emerged from a craft in Dune. Most of us spend our lives today inside a semi-permanent yet completely invisible electromagnetic fog: radio waves from antennas. Microwaves from routers. Radar from aircraft. Signals bouncing between satellites, phones, vehicles and buildings.

So the first Faraday Cage Jacket treats that electromagnetic energy the same way someone climbing Everest would treat cold weather – as something you can defend against, and insulate yourself from.  It blocks electromagnetic waves across the 0.2–14GHz range. This includes all the unseen wiring of the digital age: WiFi at 2.4GHz and 5GHz. Bluetooth at around 2.4GHz. Mobile networks. As well as higher-frequency Ku-band satellite and radar systems. In lab testing the material reaches shielding effectiveness figures of up to 92 dB – for reference this is the kind of level normally associated with secure infrastructure and electromagnetic test laboratories.

Every seam and every opening affects how energy moves across the jacket.

So the job of the design is to manage those electromagnetic fields. 

And that’s why the jacket is built from large, faceted spaceship-style panels and snap-down flaps. Overlapping sections create layered shielding zones and add 10 – 20 dB more attenuation. Each overlap is another place for energy to be redirected – another chance to keep it moving around the body instead of through it.

The jacket’s eight pockets are designed the same way. Instead of flat bags stitched onto a shell, they’re three-dimensional, origami-like bellows pockets that form enclosed volumes that behave less like pockets and more like small rooms – put a device inside one of these pockets and it’s almost impossible to track, hack or even call. So if you’re looking to shield yourself from the dystopian conditions our future digital overlords set – whether that’s surveillance, space radiation, or select parts of the electromagnetic spectrum – the Faraday Cage Jacket belongs in your future.
