X-Protect is designed to be a very tough case that offers major protection.
The case is by G-Form. They’re the folks who make those videos with iPads falling out of planes and stuff like that. Cases like this one are so protective because they have multiple layers. One is a solid outer shell that protects from bumps and scratches.
The inside layer is made of more of a gel-like substance. It is made to absorb impact when the iPhone is hit or dropped. The downside is that there is nothing there to protect the screen. While we personally don’t go for screen protectors, most of our friends who prefer these heavy-duty cases want something that offers full protection.
