Going to the beach next week and would love to have a silicon case that did NOT have the holes for the ports.

It's easy enough to remove when I need to charge or whatever but a soft case with no holes would give me a little piece of mind that I'm less likely to get water or sand into the ports.

I generally keep my phone in a zip lock bag when at the pool/beach and try not to use it much but would like something for when I need to use the phone.

Any ideas?
Other than putting tiny pieces of electrical tape over them....done that.
