Griffin Survivor Series
Griffin is a popular company that has been making cases for years. Since the old iPod days when they had wheels for navigation. The company designs each case with precision and durability in mind. They're so popular that most carriers sell them in their stores. Our favorite is the Griffin Survivor series for its durability.
Griffin is a member of the "Designed for Samsung" program. Where Samsung approves cases for use with the Galaxy S8. Griffin offers more than a few cases, so take your pick. Some are very bulky, so keep that in mind.
