Case with the most protection?

[pseudoware]

Which case provides the most protection from drops, impact, etc. I don't care how thick or bvtt-ugly it is. I'm interested in which case would allow the phone to withstand the most abuse without getting damaged.

I generally go naked, but I'm going travelling. While on the go, I likely won't be as anal as I could be about phone-safety.

Amazon.com: i-Blason Armorbox for Google Nexus 5 by LG Dual Layer Hybrid Full-body Protective Case with Front Cover and Built-in Screen Protector and Impact Resistant Bumpers (Black): Electronics looks to be the best option I've seen towards that goal, as of today - but there are likely a large number of designs yet to surface.

How about this for a dual layer, silicone and polycarbonate, case? Can't beat the price
