Signal Blocking Faraday Bag — 3 Sizes, Phone to Laptop

A sealed Faraday bag in three sizes — from a 12×20 cm phone pouch up to a 35×45 cm sack that swallows a laptop. Fold the closure over and the conductive lining blocks the wireless signals reaching whatever's inside: cellular, Wi-Fi, GPS, Bluetooth and RFID.

Choose Your Size

• 12 × 20 cm — phone, car key fob, cards, passport
• 25 × 28 cm — tablet, several devices, documents
• 35 × 45 cm — laptop, or a bag-within-a-bag for travel

What It's For

• Stopping relay theft — seal your car fob so its signal can't be picked up and relayed
• Privacy on demand — a sealed phone can't be tracked, pinged or reached
• Travel and meetings — a hard, physical off-switch rather than a software toggle
• Isolating a device you're unsure about, so it can't report anything while you decide

Details

• Material: Oxford fabric with conductive shielding lining
• Fold-over closure — no batteries, no app, no setup

Test It in 30 Seconds

Seal a phone inside and call it from another phone. No ring means it's working. Re-test now and then — seals wear, and a bag that isn't folded over fully doesn't shield.

Honest Notes

• It works only while fully sealed. Take the device out and it reconnects within seconds.
• A Faraday bag is a radio control, not a malware control — software on a device can log data while sealed and upload it later. See what a Faraday bag blocks and what it doesn't.
