DESCRIPTION Faraday sleeves are the simplest way to take your phone off the grid without switching it off. Drop it into the main compartment and close the magnetic flap all the way. While it's sealed inside, the sleeve blocks cellular, WiFi, Bluetooth, GPS and NFC signals to and from the phone. No calls, no notifications, no location pings. Take it out and it starts looking for signal again. You decide when the world gets access to you.

The lab results below are for that material, tested by Keystone Compliance, an independent test lab. They are not a test of the finished sleeve. MIL-STD-188-125-2, 10 kHz to 1 GHz: double- and triple-layer Multishield® samples were reported compliant (Report 2106-125EB, 2021). IEEE 299-2006 method, 1 to 40 GHz: a single layer of Multishield® measured 79.8 to 94.9 dB of shielding effectiveness (Report 2203-117EB-2, 2022). See the full reports on our testing page .
