Mission Darkness builds gear for law enforcement and military forensics. After testing eight different products over two years, I can tell you these aren’t consumer products pretending to block signals. They’re forensic tools that happen to work perfectly for regular people.
Every bag uses TitanRF Faraday Fabric. Lab tested and certified to MIL-STD-188-125 and IEEE 299-2006 standards. When federal agencies need to preserve evidence without corruption, they use these bags. When digital forensics labs need reliable shielding, same answer.
I tested their bags with RF meters measuring 10 MHz to 40 GHz. Complete signal blackout across every frequency. No cellular, no Wi-Fi, no Bluetooth, no GPS. Devices went completely dark the moment I sealed the closures properly.

What Sets This Brand Apart
These bags stand apart from consumer Faraday bags through verified testing, government trust, and construction quality that’s built for evidence collection rather than just privacy.
Lab Certification That Matters
Most brands claim military-grade protection. These bags actually prove it. Every bag comes with certification to MIL-STD-188-125 and IEEE 299-2006 shielding effectiveness standards. Full test reports available on request.

The TitanRF Faraday Fabric uses dual paired seam construction. Two layers of high-shielding material on all interior sides. This isn’t one thin sheet of metal fabric. This is serious construction designed to block everything from low MHz frequencies through 5G networks at 40 GHz.
Government Trust
Federal agencies buy these bags for evidence collection. Digital forensics labs use them to preserve device data during chain of custody. Corporate security teams protect sensitive equipment with the same bags.
That government/enterprise trust isn’t marketing. It’s verification. These bags work because they have to work. Evidence gets thrown out if devices are remotely wiped or altered. This construction prevents that.
Build Quality
Water-resistant ballistic nylon outer material. Heavy-duty Velcro closures. Reinforced seams. Transparent card pockets on back for ID or evidence tags. Unique serial numbers for asset tracking.

I’ve been using the same Non-Window bag for two years of daily abuse. No tears, no degradation, still blocks perfectly. Compare that to cheap Amazon bags that fall apart in three months.
Non-Window Faraday Phone Bag (2-Pack)
This Faraday phone bag is the one I recommend the most often. You get two bags with verified military-grade shielding for less than $50. One for home, one for your car. Or one for your phone, one for key fobs.

Specs
- Internal dimensions: 5.5″ x 9″ (fits large phones with bulky cases)
- External dimensions: 8.75″ x 9.5″ x 0.2″
- Weight: About 3 ounces per bag
- Two layers TitanRF Faraday Fabric, dual paired seams
- Blocks: WiFi (2.4 & 5GHz), Bluetooth, cellular (all bands including 5G), GPS, RFID, NFC, radio signals low MHz to 40GHz
- Water-resistant ballistic nylon exterior
- Secure double-roll Velcro closure
- Transparent card pocket with unique serial number
What I Tested
I sealed my iPhone 15 Pro inside and ran complete signal tests:
- Cellular: Zero bars, no reconnection attempts for 30 minutes
- Wi-Fi: MAC address invisible to router, device completely dropped from network
- Bluetooth: AirPods disconnected instantly, phone disappeared from paired devices list
- GPS: Maps showed last known position, no satellite lock possible
- NFC: Apple Pay completely disabled, couldn’t trigger contactless payment
The phone stayed dark for as long as I kept it bagged. No partial signals, no weak reconnection attempts. Complete blackout.
Who This Works For
People who need verified signal blocking without spending $100+ on premium bags. Anyone who wants a backup bag plus a primary bag. Law enforcement personnel collecting evidence. Travelers crossing borders who need device isolation.
The two-pack format is smart. Keep one at home for your car keys at night (prevents relay attacks). Keep one in your car for your phone when you park. Or give one to a family member who needs protection.
What Could Be Better
The Velcro closure wears out with heavy daily use. After a year of constant opening and closing, one of my test bags lost some grip. Still worked when sealed carefully, but required more attention.
The bags are basic looking. Black ballistic nylon with minimal branding. If you want something stylish for office use, look at SLNT instead.
No external pockets or organization. You put your device in, seal it, done. Shop Mission Darkness Non-Window 2-Pack
Non-Window Faraday Tablet Bag
Same construction as the phone bag, scaled up for tablets. Internal dimensions: 14″ x 9.5″ fits iPad Pro 12.9″, Surface Pro, and similar mid-size devices.
I tested this with an iPad Pro and a 13-inch laptop. Both fit easily. Signal blocking performed identically to all other products I tested—complete blackout across all frequencies. See the Non-Window Phone Bag section above for detailed test results.
The tablet bag is less common as a purchase because people either need phone protection or full laptop protection. But if you carry a tablet for work and need signal isolation, this hits the sweet spot.

Non-Window Laptop Bag
The laptop version scales up to 17″ x 14″ internal dimensions. Fits my 16-inch MacBook Pro with room to spare. Also accommodates multiple smaller devices or a laptop plus accessories.
Signal blocking performed identically to the phone and tablet versions—complete blackout when properly sealed. My MacBook went completely offline. WiFi disabled, Bluetooth dropped, no network visibility.
Best Use
Corporate security for traveling executives. Digital forensics labs preserving laptop evidence. Anyone carrying sensitive data on laptops who needs guaranteed signal isolation.
The professional appearance and larger size make this better for business travel than consumer backpacks. You can carry this into meetings or through airports without drawing attention.
Dry Shield Phone Sleeve
This is the waterproof version. Roll-top closure with RF welded seams. When properly sealed, this blocks all signals while keeping your phone completely dry.
Construction
- Waterproof 600D TPU and 420D TPU outer materials
- Two layers TitanRF Faraday Fabric interior
- NeoLok magnetic closure (double roll with neodymium magnets)
- Internal dimensions: 7.5″ x 4″ x 0.5″
Waterproof Testing
I stuffed the bag with paper towels and my iPhone, sealed it properly, and submerged it in my bathtub for 30 minutes. Everything stayed completely dry. No leaks, no moisture.
Signal blocking matched the regular bags. Complete blackout across all bands.
The Roll-Top Trade-Off
Access is slower than Velcro bags. You need to unroll the top, remove your device, then roll and seal again three times. Not ideal if you’re checking your phone frequently.
But if you need waterproof signal blocking, no other bag offers this combination under $50. Perfect for kayaking, boating, beach trips, or outdoor work in wet conditions.
FreeRoam Backpack
This attempts a consumer-friendly design. Drops the tactical aesthetic for a clean look that works in normal environments.
What’s Different
- Water-resistant 600D PVC exterior (not fully waterproof like Dry Shield)
- Two layers TitanRF Faraday Fabric throughout interior
- Padded laptop sleeve with Velcro securing strap
- Double roll plus spring hook closure with hidden internal magnets
- Front pocket for quick-access items
Testing Results
Complete signal blocking when sealed properly. The double-roll closure with magnets creates a secure seal. I measured zero signal leakage using the same testing methodology detailed in the Non-Window Phone Bag section.
Daily Carry Design
This doesn’t look like a military pack. You can take this to coffee shops, offices, or airports without looking like you’re about to assault something.
The capacity works for daily commuting. Laptop, tablet, phone, and essentials fit easily. But it’s smaller than the Dry Shield 40L, so don’t expect multi-day travel capacity.
The Closure Learning Curve
The double roll with spring hook and magnets is clever, but takes practice. First few times, I didn’t roll it tight enough. The seal wasn’t secure. After a week, I got the technique down.
The front pocket is too small. Barely fits a wallet and keys. They obviously designed this as an afterthought.
Best For
Daily commuters who want signal blocking without tactical appearance. Office workers who need to secure laptops during lunch or meetings. Anyone who values this shielding quality but doesn’t need waterproofing or huge capacity.
Dry Shield 40L Backpack
The biggest option. At 40 liters, this is a full-size tactical pack that happens to be a Faraday cage and fully waterproof.
Military-Grade Everything
- 500D PVC exterior (puncture-resistant and waterproof)
- Roll-top closure with clip shut seals
- Two layers TitanRF Faraday Fabric on all interior sides
- 60-80 dB average attenuation across tested frequencies
- Internal dimensions when closed: 20″ x 11″
- Weight: 5.6 pounds empty
MOLLE System
Exterior has MOLLE webbing on three sides. Includes five detachable MOLLE pouches (unshielded) and one knife/flashlight holder.
Separate MOLLE Faraday Pouches are available that snap onto the webbing. This lets you keep devices separate and individually shielded within the larger bag.
Capacity
I fit: 17-inch laptop, iPad Pro 12.9″, two phones, portable battery pack, full camera kit with three lenses, four days of clothes, toiletries, water bottle. Still had room.
The adjustable waist and chest straps make this comfortable even when fully loaded. The breathable padding on shoulders and back prevents sweat buildup during extended wear.
Waterproof Performance
I tested this in rain and near water. The roll-top seal held up perfectly. Nothing got wet inside.
Signal blocking was complete across all tested frequencies. With 40 liters of capacity, you can shield multiple devices simultaneously with room to spare.
The Weight Reality
At 5.6 pounds empty, this is heavy before you add anything. Fully loaded with electronics and supplies, you’re carrying 20+ pounds easily.
The 40-liter capacity is overkill unless you’re doing multi-day field work or need to transport large amounts of equipment. For daily use, this is too much bag.
The tactical appearance is obvious. This looks like military gear. If you’re trying to blend in or avoid attention, this isn’t subtle.
Who Needs This
Law enforcement and military personnel shielding multiple devices during evidence collection. Corporate security teams handling sensitive equipment in extreme conditions. Journalists working in hostile environments with multiple devices to protect.
Preppers who want maximum capacity in an EMP-resistant, waterproof package.
For regular people, this is probably too much. But if you know you need this level of capacity and protection, it’s the best option available.
Dry Shield 15L Tote
Mid-size waterproof option. 15-liter capacity in a tote bag format. Roll-top closure, 500D PVC exterior, two layers TitanRF fabric inside.
Adjustable and detachable shoulder strap. Load-bearing design for heavy objects.
I tested this with a laptop, tablet, and phone. All fit easily. Signal blocking matched other Dry Shield products. Complete waterproof seal when properly closed.
The tote format works better than backpacks for some people. Easier to access contents quickly. Less bulk for urban use or short trips.
Mojave Travel Case
Different approach. This is designed as a travel organizer with integrated Faraday protection rather than just a signal-blocking pouch.
The main compartment has TitanRF shielding. Two exterior accessory pockets are unshielded for items you need quick access to.
This split design is smart for travel. Put your phone in the shielded main compartment during flights or border crossings. Use exterior pockets for boarding passes, pens, charging cables.
Signal blocking in the main compartment is complete. 60-80 dB attenuation verified. The accessory pockets are not shielded, so remember which pocket blocks signals and which doesn’t.
The Tradeoffs
Exterior pockets are too small. Main compartment is snug for larger phones with cases. The multi-pocket design adds bulk compared to simple pouches.
Zipper on accessory pockets can snag. Quality isn’t as high as the main Velcro closure.
Best For
Travelers who want one case for phone and accessories with selective shielding. People who like organization and don’t want multiple separate bags.
Not ideal for daily carry if you just need basic signal blocking.
NeoLok Bags
NeoLok versions use a magnetic closure system instead of Velcro. Neodymium magnets create a strong seal with double-roll construction.
The magnetic closure is specifically designed for use with conductive gloves in forensic applications. Makes transfers inside analysis enclosures easier without damaging gloves on Velcro.
For regular consumers, the main benefit is smoother operation. One-hand opening and closing. No Velcro wear-out over time.
I tested the NeoLok phone bag. Signal blocking identical to Velcro versions. The magnetic seal is strong enough that shaking the bag vigorously didn’t pop it open.
Slightly more expensive than standard versions. Worth it if you prefer magnetic closures or need forensic-grade handling capabilities.
Charge & Shield Bags
Specialized forensic bags that keep devices powered while shielded. Includes dual-sided USB filter, NeoLok magnetic closure, and variety of charging cables.
The unique charging feature prevents lockout mode and reduces time needed to break passcodes. Enables maximum data extraction with tools like GrayKey, Cellebrite, XRY, BlackBag, Oxygen.
Available in phone and tablet sizes. Compatible with the Blocker Locker cabinet system for evidence storage.
Who This Is For
Digital forensics professionals who need devices to stay live during investigation. Law enforcement evidence collection where device access is critical.
Regular consumers don’t need this. If you just want signal blocking, buy standard bags. Charge & Shield is for specialized forensic applications.
What Happens When Things Go Wrong
Most reviews tell you when products work. This section covers what happens when you make mistakes—because understanding failure modes helps you use these bags correctly.
Incomplete Velcro Seal (Non-Window bags)
I deliberately left a 1-inch gap in the Velcro closure on my Non-Window phone bag.
Result: Phone reconnected to cellular within 30 seconds. WiFi came back intermittently. GPS maintained satellite lock.
Lesson: You need complete edge-to-edge Velcro contact. Run your finger along the entire seal to verify no gaps. Even small openings compromise the Faraday cage.
Insufficient Rolls (Dry Shield products)
I sealed the Dry Shield Phone Sleeve with only one roll instead of the required three.
Result: Bluetooth leaked through—phone stayed connected to AirPods. Cellular was partially blocked but signal strength fluctuated between one and three bars.
Lesson: Count your rolls. Three full rolls minimum, then secure the clip. Each roll matters for creating a complete seal.
Device Partially Outside the Bag
I tested with my phone’s charging cable hanging out of an unsealed corner of the Non-Window bag.
Result: The cable acted as an antenna. Phone maintained weak cellular connection. WiFi was spotty but occasionally reconnected.
Lesson: Everything must be fully inside with nothing bridging the seal. Cables, straps, headphones—anything conductive that crosses the barrier defeats the shielding.
How to Verify Your Bag Actually Works
Don’t trust marketing claims. Test your bag yourself:
- Put phone inside, seal properly following manufacturer instructions
- Call it from another phone—should go straight to voicemail without ringing
- Check Find My iPhone/Android—last location should freeze at the time you sealed the bag
- Try sending a text—should not deliver until you open the bag
- If any of these fail, reseal and test again
Red Flags Your Bag Isn’t Working
- Phone rings while bagged (instant failure indicator)
- WiFi icon still shows on device screen
- Battery drains quickly (phone is searching for signal, means it’s not fully blocked)
- GPS location updates while sealed
- Notifications appear while device is bagged
If you see any of these signs, your seal isn’t complete. Check for gaps, make sure nothing is bridging the closure, and verify you’re following the sealing instructions exactly.
The Strengths
After testing eight different products over two years, here’s what consistently impressed me.
Verified Testing
Every bag is lab certified to military standards. MIL-STD-188-125 and IEEE 299-2006 compliance. Full test reports available on request. This isn’t marketing talk. This is documented proof.
Consistent Quality
I’ve tested eight different products. Signal blocking was complete across all of them. No weak bags, no partial blocking, no failures. When they say it blocks signals, it blocks signals.
Durability
The bags last. Two years of daily use on my Non-Window phone bag. No tears, no degradation, still blocks perfectly. The ballistic nylon exterior holds up to abuse.
Smart Design Details
Unique serial numbers for asset tracking. Transparent card pockets for company information or evidence tags. Water-resistant materials protecting both devices and Faraday fabric. These details matter for professional use and don’t hurt consumer applications.
The Limitations
No product line is perfect. Here are the real limitations I found during testing.
Price Point
These bags aren’t cheap. The Non-Window 2-Pack at $48 is reasonable. But single bags at $60-$120, backpacks at $200-$300, and specialized forensic bags over $200 add up quickly.
You’re paying for verified testing, lab certification, and government-trusted construction. But budget-conscious buyers might struggle with the prices.
Limited Style Options
Everything is black ballistic nylon with minimal branding. Functional, durable, professional. But not stylish.
If you work in corporate environments where tactical bags look out of place, the FreeRoam is your only real option. Otherwise you’re carrying obviously serious gear.
Closure Wear
Velcro closures wear out with heavy daily use. After a year of constant opening and closing, expect some degradation. Still works when sealed carefully, but requires more attention.
The NeoLok magnetic versions solve this but cost more.
Access Speed
Roll-top waterproof bags (Dry Shield line) are slower to access than Velcro bags. You need to unroll, remove device, roll three times, and seal. Not ideal for frequent access.
This is the trade-off for waterproofing. If you don’t need water protection, buy standard bags for faster access.
Comparing the Competition
Understanding how these bags stack up against competitors helps you make the right choice for your needs.
OffGrid vs Mission Darkness?
OffGrid uses thermo-welded seams (stronger construction, no stitch holes). Mission Darkness uses dual paired seam construction (still very strong, slight theoretical weakness at seams).
Both offer verified government-trusted shielding. Mission Darkness has wider product range. OffGrid has cleaner aesthetic and slightly lower prices on comparable products.
I’d buy Mission Darkness for maximum product selection and proven forensic applications. I’d buy OffGrid for thermo-welded construction and better value on basic bags.
SLNT vs Mission Darkness?
SLNT is the premium option. Patent-protected technology, top-grain leather options, 100 dB+ blocking. Prices are higher for comparable products.
Mission Darkness is the workhorse option. Lab certified, government trusted, serious construction. Prices are mid-range ($50-$300 depending on product).
I’d buy SLNT for professional environments where appearance matters. I’d buy Mission Darkness for verified performance at better prices.
Faraday Defense vs Mission Darkness?
Faraday Defense uses triple-layer CYBER NC shielding (85-90 dB). Mission Darkness uses dual-layer TitanRF fabric (60-80 dB typical, can go higher).
Both block signals completely in real-world use. Faraday Defense has slight edge in measured attenuation. Mission Darkness has wider product range and longer track record.
I’d buy Faraday Defense for maximum blocking strength. I’d buy Mission Darkness for product variety and proven forensic applications.

Testing Methodology
I tested products with:
- iPhone 15 Pro with cellular, WiFi, Bluetooth enabled
- Samsung Galaxy S23 as secondary phone
- MacBook Pro 16-inch with WiFi and Bluetooth active
- Honda Accord key fob for relay attack prevention
- American Express contactless credit card for RFID testing
Equipment:
- RF signal analyzer measuring 10 MHz to 40 GHz
- Multiple WiFi routers at 2.4 and 5 GHz frequencies
- Bluetooth 5.0 devices for pairing tests
- GPS tracking software showing satellite lock status
- RFID reader for contactless card testing
Each product was tested three separate times to verify consistency. I recorded signal strength before bagging, immediately after sealing, and after five minutes sealed.
For waterproof claims on Dry Shield products, I submerged bags in bathtub for 30 minutes with paper towels and electronics inside, then checked for moisture.
Common Questions
Here are the questions I get asked most about these bags, with answers based on two years of testing.
Do these bags actually work?
Yes. Complete signal blackout in every test I ran. These are lab certified to military standards and used by federal agencies for evidence collection. They work because they have to work.
Are they worth the price?
If you need verified signal blocking, yes. The Non-Window 2-Pack at $48 is reasonable for two lab-certified bags. Premium products cost more but deliver government-trusted performance.
If you’re just testing Faraday bags for the first time, start with cheaper options like Simket. If you know you need serious protection, these bags are worth it.
How long do they last?
Two years of daily use on my Non-Window bag with no failures. The ballistic nylon holds up. Velcro closures may wear out after a year of heavy use but bags still work when sealed carefully.
NeoLok magnetic versions last longer since magnets don’t degrade like Velcro.
Will they protect against EMPs?
These bags are marketed for EMP protection. The physics works – Faraday cages direct electromagnetic pulses around the exterior rather than through to contents.
But EMP protection requires perfect sealing with no gaps. The dual paired seam construction should handle this, but I can’t test without an actual EMP.
Bags marketed specifically for EMP (like Dry Shield line) have stronger sealing. If EMP protection is your main concern, those are safer choices.
Can I use these bags on airplanes?
Yes. Faraday bags are not prohibited on flights. Many travelers use them to protect devices during border crossings or international travel.
The bags themselves don’t set off security. TSA can see inside during X-ray. No issues in my experience flying with these bags domestically and internationally.
Do they block 5G?
Yes. TitanRF Faraday Fabric blocks signals from low MHz through 40 GHz. 5G networks operate below 40 GHz, including millimeter wave bands. Complete blocking verified in my tests.
Final Verdict: Does Mission Darkness Deliver?
These bags deliver serious gear for serious applications. Federal agencies, digital forensics labs, corporate security teams, and military units trust them for evidence protection and signal isolation.
After testing eight different products over two years, I trust them too. The signal blocking works. The construction lasts. The lab certifications aren’t marketing.
The prices are higher than budget bags but lower than premium brands. You’re paying for verified performance and government-trusted quality without the luxury pricing.
- You need verified, tested signal blocking with documentation
- You value durability and professional-grade construction
- You’re protecting sensitive data or evidence
- You want the widest product selection from one trusted brand
- You need bags that law enforcement and military actually use
Skip Mission Darkness if:
- You’re just testing Faraday bags for the first time on a tight budget
- You want premium aesthetics for office environments (buy SLNT instead)
- You need the absolute strongest blocking (Faraday Defense triple-layer is slightly better)
- Budget is your main concern (OffGrid offers similar quality at lower prices on basic bags)
For most people who need reliable signal blocking, start with the Non-Window 2-Pack. Two lab-certified bags, proven performance, government-trusted construction. Best value in their entire lineup.
Test your bag when you get it. Put your phone inside, seal it, try calling it. Verify WiFi drops. Check Bluetooth disconnects. Make sure it actually works before you trust it.
The difference between a bag that works and one that doesn’t could be your privacy, your security, or your safety. These bags work.
