Silent Pocket makes faraday bags for phones, laptops, key fobs and cards: shielded pouches that instantly cut every radio connection, built by a company specializing in exactly this. When a device must go silent, an authenticated bag beats airplane mode.
Shielding works only while the seal holds, bags wear out, and quality varies across the market, which is why testing your own bag with a call is standard advice. The brand to start comparisons with.
