Mission Darkness Faraday Bag for Keyfobs (2-Pack) // RF Shielding Protective Case
Quick take
The Mission Darkness Faraday Bag (2-pack) is an RF-shielding pouch meant to help block wireless signals from key fobs and small transmitters, which can be useful if you want to reduce the chance of relay-style access when the fob is stored. Buyers generally report that their fobs or devices lose connectivity when placed inside, but fit and closure can be a little tricky with bulkier keychains, so measure first.
Pros and cons
Pros
- Multi-layer Faraday fabric design intended to block a wide range of signals, including RFID and common wireless frequencies
- Durable, water-resistant ballistic nylon exterior
- 2-bag pack is handy for pairing a spare keyfob with your primary one
- Some buyers report phone and fob connectivity drops quickly when stored in the bag
Cons
- Bag fit matters, the internal usable size is 4.5 x 3 inches, so large keychains may not close comfortably
- The flap/closure method may require tucking adjustments, especially with thicker key fobs
What buyers think
Buyer-review evidence is generally consistent on one point: the shielding effect is noticeable. Multiple reviews describe key fobs and other devices losing connection when placed in the bag, which supports the bag’s core promise of RF isolation. Reviewers also tend to mention solid build quality and a sturdy, well-made feel, with some noting that the exterior material handles water well when the bag gets splashed. The most repeated usability theme is closure and fit, where bulkier fobs or keychains can make it harder to fully seat the flap.
How this Faraday bag is supposed to help
This type of pouch is intended to reduce wireless “presence” from devices kept inside. That can matter for key fobs and small transmitters, because some vehicle theft methods rely on intercepting, relaying, or amplifying signals. Storing the fob in a shielded bag aims to limit what gets picked up from outside the bag so the car cannot “hear” it as easily when you are not actively using it.
Signal blocking coverage and materials
The bag uses three layers of high-shielding TitanRF Faraday fabric on all sides, with dual paired seam construction designed to improve signal loss. The manufacturer also claims shielding effectiveness confirmation with MIL STD 188-125 and IEEE 299-2006, and states coverage that includes WiFi (2.4 and 5GHz), Bluetooth, cell networks including 5G, GPS, RFID, and radio signals from low MHz to 40GHz.
For day-to-day durability, the outside is built from durable, water-resistant ballistic nylon. The light weight (about 3 ounces per bag) can help with storage in a console, glove box, or drawer without feeling bulky.
Size, fit, and closure are the biggest practical factors
These are universal bags, but they still have to physically fit your key set. The internal usable dimensions are 4.5 x 3 inches, so you should measure before buying, especially if your fob sits on a larger key organizer, has a bulkier shell, or is paired with multiple keys on the same ring.
Several buyers note that the flap needs to be tucked into the strap area to close properly. If your fob is “fat,” you may need a bit of adjustment to get the flap seated smoothly. If the closure is not fully engaged, you may not get the same level of isolation you expect from a Faraday pouch.
Pros and cons (in plain English)
Good fit for
- Drivers who want an extra layer of protection when storing spare key fobs or keeping a fob in a bag, backpack, or near the car
- People looking for shielding beyond vehicles, such as RFID cards or other small transmitters (as long as they fit)
- Buyers who want a 2-pack so one bag can stay near where you store keys and the other stays for spares
Consider your needs first if
- Your key fob setup is larger than the 4.5 x 3 inch internal usable space, or it makes the flap difficult to seat
- You prefer a closure style that is quick and friction-free, because the tuck-style flap may take a moment to get used to
Verdict
The Mission Darkness Faraday Bag (2-pack) is a practical option if you want to shield key fobs and small devices from wireless access while they are stored. The strongest buying signal from reviews is that it does what it claims: devices lose connectivity when inside. Just be sure to check dimensions and plan for a closure routine, especially with thicker or bulkier keychains.
Price and availability
Check current pricing and availability before ordering, since Faraday key fob bag bundles can vary by listing and promotions. If this is your first Faraday pouch, consider buying a 2-pack like this one so you have a dedicated bag for your main fob and your spare.
FAQ
Is this Faraday bag only for car key fobs?It is designed to shield key fobs and also fits small electronics and RFID-style items, as long as they fit within the internal dimensions.
Will it work if I keep my spare keyfob in the car?That is one common use case. The goal is to reduce what the car can “receive” from the fob while it is stored in the bag.
How do I know if my key fob will fit?Use the internal usable size (4.5 x 3 inches) as your baseline, and consider the thickness of your fob and any keychain bulk so you can fully close the flap.
What is the main downside?Fit and closure. The flap may require tucking into place, and bulkier key fobs may not close as smoothly.
Can I use it for RFID cards or other small transmitters?Yes, the bag is described as shielding RFID and wireless signals, but it still depends on your item size and how completely the bag is closed.
