Keep a laptop dark.
A laptop size Faraday bag with a plain black exterior that gives no sign of what is inside, lined on every interior side with two layers of shielding fabric. Slide a laptop in, roll the top over twice and press the closure shut. From that point nothing reaches the device and nothing leaves it.
Room for a laptop, or a stack of smaller devices
The opening spans the full width of the narrower side, so a laptop drops straight in and lies flat. The universal size is built to take standard laptop models, with room alongside for a tablet, a phone, and the cables and drives that came with them.
Without a laptop, the same footprint holds a lot more: multiple tablets, a handful of cell phones, transmitters, two-way radios, digital cameras, GPS units, hard drives. Soft walls rather than rigid ones give bulkier electronics room to sit, up to wireless-enabled smart home appliances.
That makes it the practical choice when a scene produces more devices than bags. Everything from one location goes into a single shielded enclosure under a single serial number.
Measure the device, not the bag. These are footprint figures, not depth. Soft walls give bulkier items room to sit.

Military-grade, start to seam
Two-layer TitanRF™
Two layers of high-shielding TitanRF Faraday Fabric on all interior sides, joined with dual paired seam construction. Lab tested and certified to MIL-STD 188-125 and IEEE 299-2006.
Large opening
The opening runs the full width of the narrower side, so a laptop goes in flat and a stack of smaller devices drops straight in. You can see what is inside and lift out one item without unloading the rest.
Double roll and Velcro
Roll the opening down twice and press the full-width Velcro closure shut. The seal runs the entire width of the bag.
Uniquely serialized
Every bag carries its own serial number, which supports evidence chain of custody and makes bags easy to track across a team.
Two transparent back pockets
A narrower Velcro-sealable card pocket for a business card, staff ID, or asset tag, and a wider open pocket beside it sized for evidence cards and paperwork.
Ballistic nylon shell
A durable ballistic nylon exterior stands up to scuffing and daily handling, keeping the Faraday fabric inside protected. It is water resistant rather than waterproof.
One bag, standing between your devices and everyone looking for them
Sealed properly, a laptop in this bag cannot be remotely wiped or triggered, cannot reach a network, and cannot hand over its microphone, camera, location or data. For an investigator that means a seized device arrives at the lab exactly as it was found, and a laptop, tablets and phones from one scene can all go dark inside a single enclosure. For an executive or a legal team it means a laptop full of privileged material stops being reachable the moment it leaves the office.
The shielding works both ways. Nothing gets out, so a device stops radiating into the room around it, which is what EMF reduction means. Nothing gets in either, so an electromagnetic pulse or solar storm cannot reach what you sealed inside. The fabric is certified to MIL-STD 188-125, the military standard for EMP hardening.

Add your agency without a silkscreen
The transparent panel on the back is split into two compartments. The narrower one seals with Velcro and holds a business card or printed label, so a bag can carry a department name without being permanently marked. The wider one sits open alongside it, sized for a chain of custody or evidence card and the paperwork that travels with a seized device.
Both stay readable without opening the bag, and either can be swapped when a bag changes hands or moves between units.
For something permanent, woven labels can be added during production instead.
Custom labeling options
Same size, or the same bag in another size
Laptop size is the largest of the three standard bag sizes. What changes between the options below is how the bag closes, whether you can see the screen, and whether it has to survive water.

The same standard, every single unit
Every bag in the line is made from the same high-shielding TitanRF Faraday Fabric, lab tested and certified against MIL-STD 188-125 and IEEE 299-2006. Every unit is uniquely serialized and wrapped in a ballistic nylon shell built to survive daily handling. The tenth bag performs exactly like the first, which is why these get ordered by the case rather than one at a time.
