OtterBox Armor iPhone Case
The OtterBox Armor iPhone case isn't specifically designed for the iPhone 5s, so it won't let you use the iPhone 5s' fingerprint reader, but for users who need a very rugged and waterproof iPhone 5s case this is one of the best options.
Users can secure the iPhone 5s in this waterproof case that can also handle drops and shocks as well. The fingerprint sensor will be covered, but users can still unlock the iPhone with a PIN.
