Griffin Survivor Strong ($30)
Griffin, once the number one iPhone accessory maker on the planet, has a few excellent cases and screen protectors for the Galaxy Note 8.
The Survivor Core passed military-grade tests and received an 810-G certification. Using this case the Galaxy Note 8 is protected from drops up to 7ft directly onto concrete. It's that strong. Seriously.
This case has a dual layer construction that's truly unique. The inside uses a strong and hard polycarbonate plastic skeleton to keep the phone safe from drops and damage. Then, the outer shell is a soft and textured TPU material to disperse damage when dropped, and makes it easier to hold.
This case is super thin and extremely light, weighing under 2 ounces, but manages to keep the phone safe even when dropped directly on concrete from over 7 feet. That's impressive. Better yet, it's cheaper than most of the big-name brands.
