Asmart Dual Rugged Case
Another popular case style is the Dual Layer Rugged Shell like this one from ASMART. You're getting a typical textured and soft TPU case that's flexible and easy to install. However, there's a second piece to the case made from reinforced hard polycarbonate plastic. This snaps on the back and gives it tons of added stability and durability.
Plus, the one has a third layer of soft TPU on the inside back of the polycarbonate shell for added grip.
