Waterproof Faraday Phone Bag

Does exactly what it promises. My phone is invisible while in my car. Only issue is it isn't heat resistant. Mistakenly left phone in bag for an hour in the car and phone was super hot.

I didn't like the fact that the bag does not have a clasp or tight closure, also the quality of the bag... seems, well, kind of cheap.

I just got the product so I haven’t tested it’s ability to block connection but the bag is really hard to roll down initially
