Two things that typically don't come together are "heavy duty" and "slim" but that's exactly what this case has to offer. TUDIA is a brand we've enjoyed in the past, especially their precision cut TPU cases.
The TUDIA Heavy Duty Slim series for the OnePlus 5 looks great and has two different layers of protection. First is a thin TPU rubberized shell that covers the entire phone. TPU helps absorb shock from drops and is very thin and lightweight. Then, there's a hard polycarbonate plastic casing that snaps on the back middle of the phone. Additionally, you can choose a few different colors for the second layer.
To make things better TUDIA added a small 2mm raised lip of TPU material around the entire screen, and the dual cameras. This means laying the phone face-down or back side down won't be a problem. The glass is protected and the camera lenses are too. Get it now in one of four colors.
