Take Control of When Your Phone Communicates
Whether your priority is protecting your privacy, safeguarding sensitive information, reducing unnecessary RF exposure while your phone is not in use, or simply deciding when your phone can communicate with the outside world, the Leblok Security Faraday Phone Bag gives you complete control.
Built upon Leblok's long-standing expertise in RF shielding, it incorporates three layers of independently tested high-performance RF shielding material to provide dependable signal isolation whenever it is correctly sealed. Manufactured in the UK and built for everyday use, it combines proven shielding performance with durable construction you can rely on.
Unlike an ordinary phone pouch, a Faraday Phone Bag creates a physical barrier between your device and external wireless signals, helping to prevent communication with mobile networks, Wi-Fi, Bluetooth, GPS and RFID systems while the bag remains securely sealed.
Whether you carry your phone for everyday use, travel, business or simply prefer greater control over your digital privacy, the Leblok Security Faraday Phone Bag provides an effective and practical solution.
Medium Model - Compact and Convenient for Everyday Carry
The Medium Faraday Phone Bag has been developed for customers who want dependable signal isolation in a more compact format. It comfortably accommodates most smartphones while remaining convenient to carry in a jacket pocket, handbag, backpack or briefcase.
Its slimmer profile makes it an excellent choice for everyday use without compromising shielding performance.
External Dimensions (Closed):
170 × 120 mm
Suitable for:
- Most smartphones
- Car key fobs
- Passport
- Other small electronic devices
As with any Faraday bag, effective shielding depends on the bag being correctly sealed using the double-fold closure.
Practical Uses for a Faraday Phone Bag
A Faraday Phone Bag offers a simple way to physically isolate your phone from external wireless signals whenever you choose. Whether you're travelling, attending confidential meetings, storing your phone while not in use, or simply prefer greater control over when it communicates, the Leblok Security Faraday Phone Bag provides dependable signal isolation whenever it is correctly sealed.
When correctly sealed, the Leblok Security Faraday Phone Bag can help you:
- Prevent communication with mobile networks.
- Block Wi-Fi, Bluetooth and GPS signals.
- Safeguard sensitive information stored on your phone.
- Prevent location tracking while your phone is inside the bag.
- Reduce unnecessary RF exposure by preventing your phone from communicating with external wireless networks while it is not in use.
- Keep your phone available for emergencies while ensuring it remains isolated until required.
- Shield compatible RFID-enabled devices from unwanted communication.
- Provide an additional layer of protection against electromagnetic pulse (EMP) events.
Simply place your phone inside the bag, fold the opening twice and fasten the security strap. Your phone remains physically isolated until you choose to remove it.
Why Choose Leblok Security?
Shielding is at the core of what Leblok does.
Long before introducing the Leblok Security range, Leblok established itself as a specialist manufacturer of EMF shielding clothing and protective products trusted by customers around the world. The same understanding of RF shielding materials, construction techniques and quality control has been carried directly into every Faraday Phone Bag.
Rather than relying on a single shielding layer, the Leblok Security Faraday Phone Bag incorporates three layers of independently tested high-performance RF shielding material, carefully bonded together and reinforced with durable stitching to provide reliable shielding performance and long-term durability.
Every Leblok Security Faraday Phone Bag is manufactured in the UK and individually inspected before leaving our factory, because dependable signal isolation relies not only on the shielding material but also on the quality of the finished construction.
Why Three Layers Matter
Not all Faraday bags are constructed in the same way.
Many Faraday bags rely on a single layer of shielding material. The Leblok Security Faraday Phone Bag uses three independently tested layers of high-performance RF shielding fabric, creating multiple shielding barriers within the bag's construction.
Combined with the dual-fold closure, this multi-layer design helps provide dependable signal isolation while maintaining excellent durability for everyday use.
The result is a Faraday Phone Bag that has been built not only to perform, but also to withstand regular daily use.
Built for Everyday Reliability
The effectiveness of a Faraday bag depends on much more than simply using conductive fabric.
Every Leblok Security Faraday Phone Bag combines carefully selected materials with precise manufacturing techniques to produce reliable, long-lasting shielding performance.
Features include:
- Triple-layer RF shielding construction
- Waterproof outer fabric
- High-strength bonded construction
- Reinforced stitching throughout
- Secure hook-and-loop fastening
- Dual-fold closure designed to minimise signal leakage
- Durable construction for repeated daily use
Every detail has been developed to deliver dependable performance while maintaining ease of use.
Independently Tested Shielding Material
Confidence in shielding performance should be based on independent testing rather than assumptions.
The RF shielding material used in the Leblok Security Faraday Phone Bag has been independently tested by the University of the Armed Forces (RF, Microwaves and RADAR Department), Germany, in accordance with internationally recognised standards:
- ASTM D-4935-10
- IEEE 299-2006
Testing demonstrates excellent shielding performance across a wide range of frequencies used by today's wireless technologies. Detailed laboratory test results are provided elsewhere on this product page for customers who wish to review the measured attenuation values.
The test result below represents the shielding performance of one layer of the material. The product is constructed with three layers of this shielding material.

No. Your phone can remain switched on inside the Faraday Phone Bag.
When the bag is correctly sealed, it physically isolates your phone from external wireless signals, preventing normal communication with mobile networks, Wi-Fi, Bluetooth, GPS and RFID systems.
Some customers prefer to switch their phone off before placing it inside the bag, while others leave it switched on. The Faraday Phone Bag performs the same function either way, provided it is correctly sealed.
No.
When the Faraday Phone Bag is correctly sealed, your phone is isolated from external wireless signals. Calls, messages and notifications will not be received while the phone remains inside the bag.
Once the phone is removed, it will reconnect to the available network, allowing new calls, messages and notifications to be received. Depending on your mobile network and phone settings, missed calls may be shown as missed calls or voicemail notifications.
As soon as your phone is removed from the bag, it begins reconnecting to available wireless networks.
Within a few moments, depending on network availability, your phone will normally reconnect to your mobile network, Wi-Fi, Bluetooth devices and other wireless services that were previously enabled.
The Leblok Security Faraday Phone Bag has been developed using the same shielding expertise that has made Leblok a trusted name in EMF shielding products for many years.
Manufactured in the UK, it combines three layers of independently tested high-performance RF shielding material with durable construction and individual quality inspection before leaving our factory.
Rather than simply using shielding fabric, every aspect of the bag's construction has been carefully considered because dependable signal isolation relies not only on the shielding material, but also on the quality of the finished construction.
