The case is comprised of 2 parts. One is the rubbery case and the other is the sturdy shell. These two parts fuse together to create a combination of comfort and protection for the phone.
This case has cut outs for the 2 cameras, flash, microphone, speaker and headphone jack. The power button is covered with a rubber button but this is still easy to press. The volume keys are also covered but again are easy to press.
The slightly rubbery texture of the case combined with the stylish design ( which can't be seen easily from the photos) makes this the ideal case for the One S.
For those considering the "barely there" case or other thin cases I recommend you consider this case instead as this case protects the corners of the phone much better than the less rugged cases.
All in all, a stylish and rugged case that provides sufficient protection without adding too much bulk to the phone.
