Best Samsung Galaxy S21 Plus rugged case: Spigen Tough Armor

Samsung Galaxy S21 Ultra Spigen Tough Armor
Keep your phone completely safe from bumps and drops with the Spigen Tough Armor. It's relatively thin for a rugged case and also comes with a built-in kickstand.


  • Good protection without the thickness
  • Allows wireless charging
  • Mil-grade certified


  • Flimsy plastic kickstand

The Tough Armor is one of the most durable cases Spigen makes, and it offers plenty of hybrid protection. You’ll find a layer of soft TPU that’s great against drops and a tough polycarbonate shell to keep scratches at bay. It even packs a built-in kickstand to prop the phone up in the landscape orientation. The kickstand is a little flimsy, though, which is a problem with a relatively heavy phone like the Galaxy S21 Ultra.
