UAG Galaxy S7 Edge Featherlight Case
Another good option is UAG, known as Urban Armor Gear. This company makes some of the most rugged and durable looking cases on the planet. Truly industrial with fake rubber "screws" and all. It takes some getting used to, and I never liked the look until I physically tried one. Once I did, I've bought a UAG case for my last 5 phones.
They have a hard armor shield and soft impact resistant core, additional durability on the corners for extra drop-protection, and are feather light. They're a bit harder than TPU, but don't feel like a typical cheap plastic polycarbonate case either. It's a perfect middle ground. The UAG Galaxy S7 Edge case comes in four fancy colors, and the link below will let you buy one, and see the industrial design we mentioned above. This is another great case worth considering.
