The best Galaxy S21 Ultra rugged cases:

Editor’s note: We’ll be sure to add to this list of the best Galaxy S21 Ultra rugged cases if new options launch.


Spigen Tough Armor

You probably expected Spigen to make an appearance on our list, and the Tough Armor offers pretty much everything you could ask for. It’s a tough, two-piece hybrid case with a soft TPU bumper on the inside. Spigen’s polycarbonate exoskeleton keeps the Galaxy S21 Ultra safe from scratches, and you can choose from black or Gunmetal finishes. A sturdy kickstand helps tie the whole case together, and you can tap into your favorite shows vertically and horizontally.

UAG Monarch

The UAG Monarch is another popular pick on many of our lists, and for a good reason. Almost all of UAG’s cases are MIL-STD 810G certified, which means they can handle more than a few drops. The Monarch is one of the most durable options around, and it protects your Galaxy S21 Ultra with heavily reinforced TPU corners. UAG’s case actually includes five layers of protection, and the internal honeycomb structure helps absorb the toughest of impacts.

Samsung Galaxy S21 Ultra rugged case

Most of our preferred rugged Galaxy S21 Ultra cases come from third-party sources, but Samsung is no slouch. Its very own rugged cover is impressive in its own right, with raised ridges and textured side rails to boost your grip. You can choose from either black or silver, and the back panel doubles as a handy kickstand for hands-free bingeing. The Samsung rugged cover also covers most of the camera unit for some extra protection.


Otterbox Defender Galaxy S21 Ultra rugged case

Otterbox has been around for as long as phones have needed rugged cases, and the Defender line is as good as it gets. While you might struggle to fit the heavy-duty protection into your pocket, Otterbox includes a handy belt holster with each case to make things easy. The Defender is primarily available in matte black, though you can choose the Varsity Blues finish if you prefer a pop of navy and green color.

Amazon

Another rugged Galaxy S21 Ultra case for you to consider comes to us by way of Supcase. The UB Pro is the company’s flagship offering, and it doesn’t skip on any of the details. While you won’t find a built-in screen protector like some models, the UB Pro still employs hybrid protection for drops and scratches. You’ll lock your phone in place with the tough polycarbonate ring, and an internal TPU bumper helps to complete the setup. Finally, Supcase’s UB Pro comes with a kickstand in the back panel.

Amazon

Our first rugged Galaxy S21 Ultra case from Poetic is the Spartan. It looks like an absolute monster thanks to the blacked-out finish and textured back panel, and it’s sure to keep your phone safe in a pinch. You’ve got a rear-mounted folding kickstand and a built-in screen protector to work with, too. If you’re not sold on black, you can choose from blue, green, and red instead.

ArmadilloTek Vanguard

The Vanguard from ArmadilloTek looks a lot like the Spartan mentioned above, though it’s smoother all around. You still get a folding kickstand, and it’s thin enough for wireless charging, but there’s no screen protector this time around. ArmadilloTek offers its flagship Galaxy S21 Ultra rugged case in black, orange, red, and even purple. It’s rated for up to 21-feet of drop resistance, but it’s safer not to test that theory.


Poetic Guardian

The last option in today’s roundup brings us back to Poetic for the Guardian. It packs a similar bumper to the Spartan, though it swaps the matte back panel for a see-through option. You can still add a pop of color around the edges, of course, but that’s not usually the point of a clear case. Poetic even built a screen protector into the Guardian, so you shouldn’t have to worry about drops from almost any angle.
