Hi all, My name is Jerry, and I am on a project to find a slim waterproof and shockproof case that would allow people to use their iphones in more outdoor situations. I know a lot of you have experiencing trying different types of cases - any particular one that you would recommend for this purpose? For disclosure, I am a product curator at a design store. We are looking for accessories that will help increase the usability of people's devices. Thanks in advance!
