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. It's an industrial design but with fake rubber "screws" on the back. It's a style some will love, and others will hate.
Each case is featherlight with a soft impact resistant core. Then the outside has pieces of hard plastic for added durability. 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 for those interested. The UAG Galaxy S7 Edge case comes in four colors. This is another great case worth considering.
If they're out of stock, consider Otterbox who has a new "thin case" the Galaxy S7 Edge Symmetry series.
