Take Control of When Your Laptop Communicates
Whether your priority is protecting your privacy, safeguarding sensitive information, reducing unnecessary RF exposure while your device is not in use, or simply deciding when your laptop can communicate with the outside world, the Leblok Security Laptop Faraday 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 laptop sleeve or protective case, a Faraday 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 use your laptop for work, travel, business, storing sensitive information or simply prefer greater control over when it communicates, the Leblok Security Laptop Faraday Bag provides an effective and practical solution.
Designed for Laptops and Larger Portable Devices
The Laptop Faraday Bag has been developed to accommodate most laptop computers while providing the same dependable signal isolation found throughout the Leblok Security Faraday range.
Its generous dimensions also make it suitable for other compatible electronic devices that fit comfortably inside while allowing the bag to be correctly folded and sealed.
External Dimensions (Closed):
480 × 370 mm
Suitable for:
- Most laptop computers
- Ultrabooks and notebooks
- Tablet computers
- Portable electronic devices
- Multiple mobile phones
- Radio equipment
As with any Faraday Bag, effective shielding depends on the bag being correctly sealed using the double-fold closure.
Practical Uses for a Laptop Faraday Bag
A Laptop Faraday Bag offers a simple way to physically isolate your device from external wireless signals whenever you choose. Whether you're travelling, attending confidential meetings, transporting business equipment, storing your laptop while not in use, or simply prefer greater control over when it communicates, the Leblok Security Laptop Faraday Bag provides dependable signal isolation whenever it is correctly sealed.
When correctly sealed, the Leblok Security Laptop Faraday Bag can help you:
- Isolate your laptop from mobile networks.
- Block Wi-Fi, Bluetooth and GPS signals from reaching your device.
- Help safeguard sensitive information stored on your laptop.
- Help prevent location tracking while your device remains inside the bag.
- Help reduce unnecessary RF exposure by preventing your device from communicating with external wireless networks while it is not in use.
- Keep your laptop ready for use whenever required while ensuring it remains isolated until needed.
- Shield compatible RFID-enabled devices from unwanted communication.
- Provide an additional layer of protection against electromagnetic pulse (EMP) events.
Simply place your device inside the bag, fold the opening twice and fasten the security strap. Your laptop 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 Bag.
Rather than relying on a single shielding layer, the Leblok Security Laptop Faraday 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 Laptop Faraday 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 Laptop Faraday 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 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 Laptop Faraday 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 Laptop Faraday 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.
