Not everyone likes bulky smartphone cases, which is why there are so many slim cases on the market. If you’ve bought Samsung’s flagship Galaxy S21 Ultra, you’re probably on the hunt for a case for your shiny new smartphone. It’s a beautiful expensive phone, and you’ll want to protect it in some way, even if you don’t want to completely plaster over its design. To help you out, we’ve compiled some of the best thin cases for the Samsung Galaxy S21 Ultra you can buy right now.

These thin cases provide a decent amount of protection without adding a lot of bulk to your smartphone. You can use these cases to protect your phone from minor scratches and dings but don’t expect them to protect your phone against major drops. If you drop your phone a lot, we suggest taking a look at the best rugged cases for the Galaxy S21 Ultra. If you’re careful with your phone and just want to add a thin layer for better grip, here are some thin cases that you can consider.

    For sustainability

    LifeProof cares for the planet and champions sustainability. That's why its Wake series case uses over 85% of ocean-based recycled plastic. Still, the case provides ample protection against scratches, drops, and bumps.

Whatever you may want, there’s a case for everyone. Spigen and Otterbox are two of the best names in the business, while Nillkin, Ringke, and UAG also make some great quality cases. You can also pair a thin case with a screen protector for some added protection in case of a drop.
