Best Faraday Bags of 2025: Signal-Proof Picks for Phones, Laptops & Go-Bags

Your digital devices constantly send and receive signals without your knowledge or consent. Your smartphone pings nearby cell towers, car key fobs remain vulnerable to relay attacks, and laptops broadcast their location. All these radio frequency emissions compromise privacy and security in ways most people overlook.

Faraday bags, named after physicist Michael Faraday, who pioneered electromagnetic shielding, offer a simple physical solution to this invisible problem.

These specialized pouches, sleeves, and backpacks block electromagnetic signals like Wi-Fi, Bluetooth, cellular, GPS, RFID, and NFC, creating a “blackout zone” that keeps your devices truly disconnected when needed.

As cybersecurity experts at Batten Cyber, we’ve tested dozens of these signal-blocking solutions to identify which ones actually deliver on their promises.

This guide helps you understand the technology behind Faraday protection and showcases the best options available in 2025 for various needs and situations.

What Are Faraday Bags and How Do They Work?

Faraday bags are portable pouches that block wireless signals by using radio frequency (RF) shielding. They work on the same principle as a Faraday cage, a conductive barrier that redistributes electrical charges to block electromagnetic fields.

High-quality Faraday bags contain multiple layers of conductive materials like copper, silver, or nickel, enclosed by durable outer fabrics. When electromagnetic waves hit this mesh, they generate opposing currents that cancel the signal.

A bag’s effectiveness is measured in decibels (dB) of attenuation. For example, 60dB reduces a signal to one-millionth of its strength, while 80dB cuts it to one-hundred-millionth. The best Faraday bags block a wide range of frequencies, from 700MHz (cellular) to 5GHz (Wi-Fi) and upto 24–40GHz for high-band 5G.

This physical layer of protection complements digital security measures like those outlined in our guide to making your computer hack-proof.

When Would You Need a Faraday Bag?

Understanding when to use a Faraday bag is essential for making an informed purchase decision. Here are practical scenarios where these signal-blocking tools prove their worth:

For the Global Traveler

International travelers face heightened digital privacy risks. Customs agents can access or clone device data, and powering on your phone in a new country may trigger auto-connections to insecure networks.

Studies show that up to 90% of international travelers engage in risky behavior when traveling abroad in terms of their wireless devices, leaving the majority of travelers open to cyber attacks.

Using a Faraday bag prevents remote wiping, unauthorized access, and location tracking. This is especially useful when traveling through regions with poor data privacy laws or industrial espionage concerns. Paired with a secure VPN, it offers strong digital protection.

For the Remote Worker or Business Professional

If you handle sensitive client, financial, or proprietary data, a Faraday bag can prevent wireless breaches during commutes, off-site meetings, or personal travel. For remote professionals, combining Faraday protection with a secure guest Wi-Fi and identity theft tools forms a robust defense.

According to Business Insider, hackers can use RFID scanners to access signals from employee badges and gain illegal access into physical office spaces, and even worse, they can do so with simple electronic devices purchased from Amazon.

For Everyday Privacy and Security

Faraday bags also help everyday users. They block relay attacks on car key fobs, prevent smartphone location tracking, and protect RFID-enabled cards and passports. A Pew Research study found 79% of Americans worry about corporate data collection, yet few take action. A Faraday bag offers a simple, effective step toward real digital privacy.

What to Look for in a Quality Faraday Bag

Not all Faraday bags are created equal. To ensure real signal protection, focus on these critical factors:

Signal Attenuation Performance

Attenuation is the core function of a Faraday bag. For general privacy, look for at least 60dB of signal reduction, which blocks common communication signals like Wi-Fi, Bluetooth, and cellular.

For higher-risk scenarios, such as safeguarding government data, trade secrets, or critical infrastructure devices, bags should offer 80–100dB of attenuation, reducing signal strength by up to one hundred-millionth.
A quality manufacturer will publish verified attenuation test results across relevant frequency ranges (e.g., 700MHz to 40GHz). Vague marketing language like “military-grade” without technical data is a red flag.

Laboratory and Military-Standard Testing

Reputable Faraday bags undergo independent lab testing and may meet MIL-STD-188-125, a U.S. military standard for electromagnetic pulse (EMP) shielding.

This ensures reliable performance under extreme signal exposure. Many low-cost alternatives fail to block high-frequency 5GHz or millimeter-wave 5G signals in real-world testing, despite advertising otherwise.

Construction and Closure Quality

Real protection depends on physical design. Prioritize bags with:

• Water-resistant or weatherproof exteriors
• Double-stitched seams
• Overlapping inner layers at closure points
• Shielded, waterproof zippers or roll-down closures (avoid velcro, which leaks signal)

These features prevent signal leakage and ensure durability in field or travel use.

Size and Device Compatibility

Choose a form factor that fits your needs, such as small pouches for smartphones or key fobs, mid-size bags for tablets, or full-size backpacks that accommodate laptops and multiple devices. Ensure the bag is large enough to enclose the entire device within the shielded area, not just partially.
