Looks awesome. Been wanting something with this style of back so opted to not get carbon this time. Karbon looks a lot thinner than this version
I believe it is thinner than the Ballistic Nylon. Just take a look at the camera cutout; the Karbon protrudes out. The packaging also states its .75mm thick.
It also seems to have a "rubberish" feeling all around the case, including the back.
