Communications & EMP
Waterproof EMP Faraday Backpack (30 Liter)

As a ham radio operator, I think a lot about how we'd communicate if the electronics we depend on stopped working. A Faraday bag is a simple layer of protection. It's lined to block electromagnetic energy, so the devices inside are shielded from an EMP or a severe solar storm.
This one is a waterproof 30-liter backpack, big enough for a backup radio, a spare phone, a small charger, and a flash drive with copies of your important family documents. I don't own this exact pack, but it's the kind of thing I'd use for my own backup communications gear. I'd rather have it and never need it.
