The iLuv Skin Case is definitely an extremely thin case. It is made of a soft rubber silicon material that feels extremely smooth to the touch. Some people may be willing to sacrifice a little bit of protection to have a thinner more portable case but in my opinion, this case was more than a little too thin.
If you want something extremely thin and don't plan on transporting your iPad very far in this case, you should be okay. Other than that, this case is more for looks than anything else.
