Carl, it's tempered glass, not gorilla glass. I used to use the otter box case but a couple of years ago switched to UAG. Awesome cases, rubber bumpers and smooth so they fit in a pocket. I do t wear my phone on my belt and keep it in my back pocket at home and in a breast pocket at work. Slides in and out smoothly whereas my otter box would get stuck because of the size and the rubber over molding.
