Spigen Slim Armor Kickstand for Galaxy S7 Edge
Spigen is a popular case manufacturer with more than a few we would recommend. The Slim Armor is the best overall option in terms of protection and bulk.
The company uses a unique dual-layer design to build each case. There is a soft shock absorbing TPU material on the inside, then a hard polycarbonate plastic shell on the outside. Spigen then added a kickstand for convenience. This case isn't too thick but it's also not so thin that you're worried about damage.
