SLNT Silent Faraday Sleeves Multi-shield for Phones (Medium)

Perfect description 100% accurate

This was brought for my brother after he told me he wrapped his phone in foil.. did a test with his method and a silent pocket.. after the results were in he wanted one immediately.. well worth it if you just do not want to be tracked but want the security of a mobile if needed when you are out and about, not everyone wants a phone permanently attached to their hand..
