X-Doria Galaxy S8 Defense Case ($35)
X-Doria is a new brand many seem to enjoy. The company uses three different materials to make each case durable. They are all military grade drop-tested and approved. Inside is a soft TPU material that absorbs damage if dropped. Then they add a polycarbonate shell on the outside and cover it in aluminum.
Each case comes in PU leather or carbon fiber for added styling.
