Triple Layer EMP & Signal Blocking Protection for Laptops
The Leblok Faraday Laptop Bag delivers unmatched protection for portable computers and sensitive data. Using three layers of ultra-high attenuation shielding fabric, it forms a complete Faraday cage that blocks electromagnetic signals. This design also provides EMP protection through triple-layer shielding – a performance level rarely matched in typical Faraday pouches.
Constructed from water-resistant, rip-stop fabric with precision stitching, this bag is lightweight yet robust — ideal for defence, research, or corporate security use.

Frequently Asked Questions
How does the Faraday Laptop Bag secure my device?
The Faraday Laptop Bag isolates your laptop from all external wireless communication by using three layers of high-performance conductive fabric. When properly sealed, it provides over 100 dB attenuation across WiFi, Bluetooth, cellular, and GPS frequencies, preventing remote access and data leakage.
Does it provide EMP and EMF protection?
Yes. The triple-layer shielding fabric offers verified attenuation against electromagnetic pulses (EMP), EMF exposure, and radio-frequency interference (RFI). Independent testing to ASTM D-4935-10 and IEEE 299-2006 standards confirms its performance for professional and defence-level use.
Will my laptop battery discharge faster inside the bag?
Modern laptops are designed to manage power efficiently, so the bag itself does not make the battery discharge faster. When WiFi or Bluetooth are left on, the laptop may briefly keep searching for networks while sealed in the bag, which can cause a small amount of extra drain, but this is usually minimal and does not harm the device or its battery.
Is the Faraday Laptop Bag suitable for travel or field operations?
Absolutely. Its robust, water-resistant rip-stop construction and reinforced folding closure make it ideal for secure transport, travel, or field environments where data protection and operational confidentiality are critical.
What level of signal shielding does the bag deliver?
The bag achieves over 100 dB attenuation at 2.4 GHz and 5 GHz (WiFi and Bluetooth bands) and across cellular and GPS frequencies.
