Need to find a thick and durable case for HTC Droid Incredible?

I have an HTC Droid Incredible and I dropped my phone and cracked the screen twice now and we have replaced the screen on it both times. I am looking to buy a durable phone cover that will break the fall in case I accidentally drop my phone again. I DO NOT want an Otter Box, or a Body Glove. I would like to find something that is thick and made of some kind of rubber or silicone. Right now I have an Amzer cover in the phone right now and it is not very thick and I don't think it will protect my phone that much. I don't want hard plastic, I want something soft that will, as I said, break the fall incase I drop it again. Any ideas about where I could find something like that? It needs to be rubbery or made of silicone and I would like for it to be thicker than those silicone soft cases that you find everywhere. Thanks!
