The GoDark® Faraday Crossbody Bag is a stylish, everyday carry solution engineered to block all wireless signals — including cellular, GPS, Wi-Fi, Bluetooth, and RFID — from reaching the devices stored inside. Built around proven Faraday shielding technology, the bag effectively creates a portable signal-dead zone, preventing remote tracking, hacking, and unauthorized data access without requiring you to power down your devices.
Designed for security professionals, investigators, attorneys, executives, and privacy-conscious individuals, it offers discreet protection during sensitive meetings, travel, or any situation where digital surveillance is a concern. The crossbody form factor makes it practical for daily use while keeping your phone, key fobs, passport, and other electronics completely isolated from outside networks.
- Blocks cellular, GPS, Wi-Fi, Bluetooth, and RFID signals simultaneously
- Prevents remote tracking, eavesdropping, and unauthorized device access
- Discreet, wearable design suitable for everyday professional use
- Ideal for protecting key fobs, smartphones, passports, and payment cards
Shielding you will actually carry
The practical failure of most Faraday products is not performance. It is that they live in a drawer. A bag that has to be found, unpacked and deployed is a bag that gets skipped on the day it would have mattered.
A crossbody puts the shielding into the thing you are already carrying. The phone goes into the shielded compartment as a matter of routine rather than as a decision, which converts an occasional precaution into a habit. For an investigator moving between locations, a protective detail, an attorney travelling to a sensitive meeting, or anyone who simply does not want their movements logged continuously, that shift from deliberate act to default behaviour is the whole value.
How the shielding works
The shielded compartment is a conductive enclosure. With the device inside and the closure made correctly, cellular, Wi-Fi, Bluetooth and satellite positioning are all blocked in both directions. The device cannot reach a network and no network can reach the device — not because software says so, but because the radio energy cannot cross the barrier.
That is the difference from airplane mode, and it is the reason this category exists. A software state can be overridden by management policy, ignored by a compromised device, or re-enabled by an update or a scheduled task. A conductive enclosure has no such failure mode.
Carrying it well
A few habits make the difference between owning one and using one.
Decide what lives in the shielded compartment. Phone, certainly. A car key fob is the other obvious candidate — keyless-entry relay theft is a real and growing attack, and a fob inside a Faraday enclosure is immune to it. Access badges and contactless cards are worth including if skimming is a concern in your environment.
Keep the unshielded pockets for what needs to stay reachable. Most people want one device live and the rest dark; a bag with both kinds of compartment lets you do that without carrying two bags.
Close it properly, every time. The seal is the product. A partial fold or a lifted corner is a gap, and radio needs very little. Make the closure a deliberate motion rather than a rushed one.
Plan where you open it. A device that has been dark reconnects and reports its position immediately on emerging. If the point of the shield was not being tracked to a location, the bag should be opened somewhere that does not undo the exercise.
Verify it, repeatedly
Test before you rely on it and every few months afterwards. Seal the phone in the shielded compartment, then call it from another phone: it should go straight to voicemail with no ring. A missed test is how people discover, after the fact, that a worn bag stopped shielding months ago.
Conductive fabric degrades where it is creased repeatedly, and a bag carried daily creases in the same places constantly. That is the trade-off for convenience, and it is manageable — it simply means the test is a routine rather than a one-off.
What to expect from the device
Battery drains faster inside the shield. A phone that cannot find a network raises transmit power while it searches, so a long shield costs charge; plan for it if you are dark for hours rather than minutes.
And be realistic about consequences. Shielded means unreachable — no calls, no messages, no location sharing with people who may be expecting it. If someone needs to be able to reach you, tell them in advance rather than leaving them to wonder.
Who this suits
Investigators working surveillance, where a phone reporting position continuously is a liability to the work. Protective details moving a principal. Attorneys and executives travelling to discussions they would rather not have logged. Journalists and anyone handling a source relationship. And ordinary people who have simply decided they would rather choose when their devices are reachable.
It also suits the household use nobody expects: a bag by the door for key fobs, defeating relay theft with no batteries, no subscription and no configuration.
Care
Store it loosely rather than compressed under weight. Keep sharp objects out of the shielded compartment — a puncture in the conductive layer is a breach whether or not it is visible. Keep it out of a hot vehicle where you can. Inspect the closure surfaces for wear, and retest with the call check on a schedule.
The boundary
It controls reachability while a device is sealed inside it, and nothing else. It does not remove malware, undo a compromise, or protect an account that anyone with the password can reach from anywhere, and it is not a substitute for a strong passcode and device encryption if the phone is simply taken.
If a device is suspected of being compromised rather than merely trackable, shielding preserves the state — and the right next step is examination rather than a return to normal use. Our digital forensics team handles that part.
