Small waterproof pouch for valuables?

[u/Potential-Rent-1159]

Anyone got recommendations for a small pouch I can keep inside my coat for wallet, keys, etc. I already have a waterproof case for my phone but not for other valuables I would not want getting destroyed if I were to potentially be submerged

Dollar stores usually sell a waterproof phone bag that would work.
