RhinoShield CrashGuard NX is a unique bumper case. Since both the frame and the buttons are interchangeable, you can customize the case to match your personal style. The bumper-style case only covers the edges of your smartphone, allowing you to either maintain the original design of the smartphone or combine it with a skin. Of course, the CrashGuard NX provides the same excellent impact protection you expect from RhinoShield. RhinoShield's proprietary ShockSpread material offers impact protection from 3.5 meters, even though it is 20% thinner than other cases that provide a similar level of protection. The CrashGuard NX frame is compatible with Mod NX backplates, meaning you can remove the frame and attach a backplate to transform your bumper into a standard case with a backplate. Mod NX backplates are sold separately.
