Mission Darkness NeoLok Window Faraday Bag for Phones signal blocking cell phone protection

Keep Cell Phones and Small Devices Shielded


The Mission Darkness™ NeoLok™ Window Faraday Bag for Phones completely blocks all wireless signals and keeps small sized electronic devices shielded to prevent hacking, tracking, spying, and chain of custody corruption. When a cell phone is properly enclosed in the bag, no apps or malicious code can be remotely triggered or wiped, no communication can penetrate, and no one can access the microphone, camera, GPS location, or data.

The bag is built with a durable and water-resistant ballistic nylon outer material to ensure that devices and faraday fabric stay dry and protected. The interior includes two layers of high-shielding TitanRF™ Faraday Fabric on all sides with dual paired seam construction. The large preview window allows the user to view contents inside, device battery life, and confirm signal cutoff. The bag will block all wireless signals including WiFi (2.4 & 5GHz), Bluetooth, cell signals including 5G networks, GPS, RFID, NFC, and radio signals from low MHz to 40GHz. Additional product features include a NeoLok magnetic closure, unique serial number, and transparent branding pocket.

The patented NeoLok closure system allows an operator to effortlessly close the bag by way of a double roll and strong magnetic seal holding the roll in place. A quick-snap strap over the roll provides extra closure protection. The quick-snap strap should be used when transporting the bag, but can be undone upon introducing the bag into an analysis enclosure. From there, the user can easily open the bag with a glove one-handed if need be. This is a feature primarily designed for forensic investigators, eliminating the risk of puncturing an analysis enclosure glove with scissors (often used to cut a faraday bag open) or harsh Velcro (used in standard faraday bag closures).

The NeoLok Faraday Bag offers extreme device protection, security, and ease of use. It is compatible with Mission Darkness analysis enclosures such as the BlockBox Lab XL and the BlockBox Touch Series.

The patented NeoLok magnetic closure system allows the user to effortlessly close the bag with a double roll magnetic seal to maintain military-grade shielding

Patented NeoLok™ Magnetic Closure

NeoLok faraday bags are specifically designed to be used for transferring devices from the collection site to the lab. The bag's magnetic closure easily opens inside of an analysis enclosure or forensic box without the worry of damaging conductive gloves, opposed to Velcro closure bags which can cause abrasion.

Transparent Preview Window

The large preview window allows the user to view contents inside, device battery life, and confirm signal cutoff. It does not enable you to operate touch screens through the window.

Easily Add Department/Agency Info

Mission Darkness faraday bags have a Velcro-sealable pocket on the back to place a business card or more permanent sticker. There is no need to silkscreen your department information on the bag. If you would like a permanent way to custom brand bags, we can add woven labels during production. Please contact us to discuss options.

Usage Steps

1) Place device inside the faraday bag (make sure the screen faces out the window)

2) Roll the top twice evenly so that the magnetic seal plus makes complete contact

3) Use the snap button to keep the roll in place (recommended during transport)

Best ones we tried

Tried a few faraday pouches. These were the best all around. Attention to detail makes them very usable. Definitely worth the higher price.

Great cell blocker

Very good

Excellent product

I appreciate the thickness of this Faraday bag, it does the job of blocking any and all signals well. I tested it and was pleased it was unresponsive when called from an outside phone. I could also see the screen through the window.
