Product Description


The Mission Darkness™ Dry Shield Faraday Backpack 40L completely blocks all wireless signals and keeps large electronic devices shielded to prevent hacking, tracking, spying, and chain of custody corruption. When a device is properly enclosed in the bag, no apps or malicious code can be remotely triggered or wiped, no communication can penetrate, and no one can access the microphone, camera, GPS location, or data. Primary uses are for law enforcement and military forensic evidence collection, defense against data theft, personal security, EMP protection, and to enhance digital privacy. The large 40-liter capacity can accommodate numerous devices, such as laptops, batteries, tablets, cell phones, radios, GPS units, and additional accessories and gear. Electronics enclosed inside are guaranteed to remain dry and offline in any water-surrounded location.

The military-grade tactical backpack is built with a durable and waterproof 500D PVC outer material and two layers of high-shielding TitanRF Faraday Fabric on all interior sides with dual paired seam construction. It includes adjustable waist and chest straps, breathable padded shoulder straps, and breathable padding for the upper and lower back, making it comfortable for long-term use in the field. The pack comes equipped with MOLLE webbing on three sides, five detachable MOLLE pouches (unshielded), and one holder for a knife or flashlight. The MOLLE system allows you to customize the pouch arrangement or add any snap-on MOLLE packs, gear, carabiners, and accessories. It is compatible with the Mission Darkness™ Dry Shield MOLLE Faraday Pouch (waterproof version) and the Mission Darkness™ MOLLE Faraday Pouch (standard version), which utilizes the quick snap system to attach shielded pouches to MOLLE webbing, enabling users to keep devices separate and secure. Add numerous MOLLE Faraday Pouches to your order for additional shielded compartments and isolation.
