Cellular, WiFi, Bluetooth, GPS, NFC — every radio in your pocket pings every few seconds. Drop your phone in. Sealed. Silent.
Triple-layer signal-blocking pouch — silver-coated rip-stop nylon outer, conductive shielding mesh, EMP-grade liner. Roll-top closure with hook-and-loop seal. Lab-tested ≥80 dB attenuation across the bands every consumer phone uses. Holds up to a 7" device.
Triple-layer shielded fabric, Velcro + roll seal, fits phones up to 7". Ships in 24h from Austin.
We're not interested in scaring you. These are documented systems with public deployment records, vendor specs, and academic studies on their failure modes. Pick a problem; we'll tell you which gear addresses it.
Your phone broadcasts probe requests for known Wi-Fi networks. Carriers triangulate cell-tower handoffs every few seconds. Key fobs leak rolling codes that relay-attack tools can replay. AirTag-class beacons ride your pocket without consent. A Faraday pouch stops all of it, instantly.
Privately-operated camera networks log plates, vehicle make, color, and direction at intersections, then share that data across agencies. EFF's Atlas of Surveillance maps thousands of deployments across US cities.
Most security cameras flood a scene with 850nm or 940nm IR light to keep a clean image at night. Smartphones do the same to map your face. Standard sunglasses are transparent to it; ours block it.
Laptop and IoT mics can be activated by software vulnerabilities or platform-level features. A USB mic-blocker spoofs an active audio device so the OS routes capture into a dead end. Hardware-level — no driver, no app.
Anything visible from 30° off-axis is visible to a phone camera at 6 meters. Privacy filters reduce viewing cone to ±30°. Underrated, cheap, immediate.
Hardware buys you a layer. The other layer is your data exhaust — broker records, app trackers, public-records aggregators. We don't sell software, but our field guide has the playbook we use ourselves.
Everything we sell, we use. No fear-marketing kitchen sink — these are the items that survive the test of "would I actually carry this every day."
Every UNS-FB1 lot is sampled and tested in a calibrated shielded chamber at our partner ISO/IEC 17025 lab using a vector network analyzer (Keysight E5063A). Below is the as-measured attenuation curve from lot 0526-12. PDF includes raw S21 sweeps, S/N traceability, and methodology.
≥80 dB attenuation target met across the full 700 MHz–6 GHz consumer-phone span. Cellular LTE/5G low-band, 2.4/5 GHz WiFi, BLE, and GPS L1 (1.575 GHz) all sit deep below the noise floor of an unsealed receiver.
Reviews are tied to a serialized order ID and a US shipping address. We don't run incentivized review programs — these are unpaid customers who agreed to be quoted.
"Tested it the obvious way — dropped my phone in, called it from my wife's. Straight to voicemail. Tried Find My from a laptop — last seen, still our living room from an hour ago. Exactly as advertised."
"Quality is genuinely good. Triple-layer feels substantial without being bulky. Roll-top seal is the reason I bought this over the cheap mesh sleeves on Amazon — those leak."
"Bag does exactly what it claims. I keep it in my work bag. Only knock — wish the larger size fit a tablet without folding it. Maybe a tablet version?"
If yours isn't here, write us. A real person replies within one business day, from a US email address, with their first name on it.
No. That's the point. Cellular, WiFi, BLE, GPS, and NFC are all attenuated below the receiver's noise floor — your phone is functionally off the network. Anything that happens during that window queues up and delivers when you take it out.
Airplane mode is a software toggle. Software toggles can be bypassed, ignored by background processes, or turn back on without your knowledge. The bag is a physical Faraday cage — radios can't transmit even when the phone tries.
Yes — and you can verify it. GPS L1 is at 1.575 GHz, well within our attenuation band. Open Maps with the phone in the bag and you'll either lose lock entirely or see your position freeze on the last fix.
Up to a 7" device — every iPhone (incl. Pro Max) and most Galaxy/Pixel handsets, with room for a slim case. The bag itself is 8.5" × 5" × 0.4" sealed.
All orders ship from our Austin, TX warehouse. Standard is 2–5 business days via USPS, free over $60. Express is 1–2 days for $9.
30 days, no questions, prepaid label. If a unit fails our spec under normal use within a year, we replace it.
