What is the life of a Faraday bag?

The useful life of a Faraday bag depends on many factors, including frequency of use, environmental conditions, and care. OffGrid  bags have multilayers of fabric and an exterior layer of protection against water and humidity that protects the devices within the bag and extend its useful life. We recommend that a bag be evaluated regularly for wear and tear, for  oxidation of the Faraday material, and for tears or punctures that might compromise the integrity of the shielding.
