Otter Box, the three piece one, is a fantastic case. Not quite waterproof but definitely great drop protection and dust protection. The tradeoff is doubling the bulk of the phone. It's overkill for most people. I went with the spigen slim armor and that was enough for some short drops and covered tossing onto tables. You need a case but have to decide how much case you need. 2 cases nay be the way to go if you have different needs at times.
