Tech21 EVO Check ($40)
The Tech21 EVO Check case might not be the most stylish or best-looking thing you've ever seen, but it does keep your phone very very safe.
Each case from Tech21 uses a special patented material that lines the inside of the case. This stuff is crazy strong, can absorb impacts far greater than a typical drop from your waist or ear, and it's super thin.
Tech21 cases have a thin profile, reinforced corners and edges, oversized tactile buttons that are easy to press, and textured dot-matrix design on the back for added grip. Plus, they add a built-in antimicrobial that helps keep your case hygienically clean.
