The physics is 190 years old and unbeatable. We just made it wearable.
Three ideas explain everything we make. Once you see them, you will never look at a phone the same way.
Radio is light you cannot see. Both are the same thing: electric fields rippling through space. Your phone, your wifi, your GPS satellite, the sunlight on the table: one family of waves, different lengths. Nothing mystical, all measurable.
A prism splits one beam into many colors because each wavelength bends differently. Wavelength decides everything: long waves pass through walls, short ones carry data. 5G, LTE and Bluetooth are just colors of radio, and like every color, a wall can stop them.
Your phone and the tower shout at each other constantly, even when you sleep. That two-way shouting is how networks find you, price you and follow you. Wrap the phone in a conductive cage and the shout never arrives. Silence is not a setting. It is geometry.
Eight bags and pouches, sewn by hand. Each closes over the cage completely, because a Faraday cage with a gap is just a bag.

Belt-worn. Phone drawn in one move, sealed in one fold.

Your phone talks to towers, satellites, beacons and apps around the clock. It does this in your pocket, on your nightstand, in your meetings. Airplane mode is a promise from the same companies that monetize your location. A Faraday cage is not a promise. It is physics.
Every Shield piece is handmade, lined with silver-plated polyamide fabric woven in Germany, attenuating 60 dB and more from 200 MHz to 14 GHz: 5G, LTE, GPS, wifi, Bluetooth, NFC. Journalists crossing borders, lawyers in negotiations, recording artists, parents teaching kids what attention feels like: they all need one moment where the device is simply not there.
Uncertainty, by design.
The drawing is free. If you love it, we make it by hand and ship it worldwide.
