LifeProof Slam Clear Case
If you're looking for a case from a brand you might know or recognize, consider the LifeProof Slam. They offer cases that are a little more expensive than most, but they're always extremely durable. This company got popular due to water-proof cases, but we don't need that anymore on the Galaxy S9.
As a result, they're offering a strong clear case that can survive drops onto hard concrete from over 2 meters high. They're precision molded for a sleek finish and reinforced on the edges with a soft TPU shell.
Lifeproof offers this clear case with a black and lime green bumper, or clear and pink for the ladies.
