Spigen Ultra Fit
The Spigen Smooth Ultra Fit is very similar to the case mentioned prior, only it has one layer and is a matte black hard case. Rather than be a TPU material it's a hard plastic, but has a slip-resistant matte textured finish. Oh, and it has all the cutouts you'd expect to access all buttons or ports.
The benefit here is this case is much cheaper, coming in around $9.00 depending on the color, and is also available from Amazon in six different colors.
