Samsung Galaxy S21 Ultra Spigen Thin Fit
The Spigen Thin Fit is a thin and light case that will help keep the phone scratch-free. For drop protection, you might want to check out the more protective cases on this list.

Pros:

  • Thin and light
  • Tactile button covers
  • Precise cutouts

Cons:

  • Not as protective
  • Only one color option (black)
  • Not the easiest to remove

If you’re looking for a thin and light case, this case’s name is self-explanatory. The Spigen Spigen Thin Fit is a polycarbonate case that snaps onto the phone. It comes with a raised camera bump, button covers, and precise cutouts for everything else. Despite being a hardshell case, it also offers an impressive grip. That said, it’s not the best option if you’re particularly clumsy. However, it can manage the occasional bump or drop.
