Finding the right case depends on if you want it to be bulky, rubbery, plastic, or slim. Life proof cases are fantastic for going to the beach or going swimming and all that but the rubbery stuff fades very quickly and starts to look not very nice. all of these cases are very protective against drops.
- If you want a rubbery case i recommend the Griffin survivor. if you go on their website you can customize the cases to your liking.
- If you want a bulky case then i would recommend the otter box defender or also the otter box commuter (which is not as bulky but still has the same amount of protection.) you can also customize these cases on their website.
- Im not personally a fan of plastic cases but incipio makes very nice cases with lots of colors to choose from. speck also has very nice cases and losts of colors
- For the slim cases which i like the most. Currently i have a Caseology Wavelength on my 6s. It protects against stops and the lips is raised so when sitting on the table the screen doesn't touch the table. on their website there are quite a few color combinations to choose from.
All of these cases can be found on amazon for cheap.
