Tech21 Evo Check for Galaxy Note 9
Another brand that makes excellent cases is Tech21. This case is thin, lightweight, durable, and uses a checkered pattern that helps disperse force from drops and other accidents.
This company uses a patented FlexShock material on the inside of each case, air-cushion corners, and reinforced bumpers to ensure your phone stays safe. So much, in fact, that they promise 3m/10ft drop protection on every case they make. It comes with a lifetime warranty and is available in multiple different color choices. They also have a sleek wallet case if you're interested.
