If you’re looking for an extremely minimal case for your 6 series iPhone, then take a look at the eXo Case for iPhone 6/6 Plus ($130). The case features an extremely strong stainless steel skeleton and an impact absorption system. The arms of the case wrap around your phone and provide an ergonomic texture that makes your iPhone much easier to grip and handle. It also comes with a clover cutout so you can utilize compatible accessories like belt clips or dashboard mounts. If you want a less expensive case with a similar design, then check out the write-up we did for the Radius V2 iPhone Case ($70+).
