The G-Form Extreme folio is made from a spongy type substance without the holes. It comes available in yellow or black colors. The folio style is my personal favorite type of all the iPad case selections. I like the variety of the many different viewing angles it offers. G-Form uses proprietary RPT technology and Poron XRD material to absorb energy while protecting the iPad from impact. Its products are all made with the intentions of protecting the iPad at all cost. I haven’t seen any other cases on the market offer more protection ability.
