This might not be what you're looking for but you should check out the UAG Monarch. It's not a dual layer per say, but it protects like one since it has the back brace, which absorbs shocks if you ever drop it--not to mention the corners are slightly beefed up without making the case look ugly. Good honey comb pattern grips on that sides that are functional and look cool, so you won't drop it in the first place. Great buttons, great lip around the screen with a screen protector.
It's a very "masculine" looking phone case... so if that doesn't bother you, I would absolutely recommend it. I think it looks awesome and it's very protective without being Defender Pro level of bulky. You can also get it in a leather version to make it look more "classy" for every day use vs the Carbon Fiber look.
