Does the iPhone 4s really need a full body case?

I've always used an Otterbox Defender with it but it's so bulky. I drop my phone a lot and don't have insurance. Any case suggestions that are sleeker?

Well, I personally like bumpers better for the iPhone. However, if you drop your phone a bit, I would get a case protector that covers at least the sides and back. Replacing the iPhone lcd screen is easy but cost a little bit of money for the part. So if you do not want to replace your iphone glass screen, get a better case. If you are ok with replacing your screen, get what you want.

You are right, the otterbox is great but bulky. You can try this case, it warks as well as the otterbox
