It is thin enough to fully take advantage of the slimness of the iPad Air while still offering protection when the case is closed. I did have a little trouble getting the latch to release but finally figured out that squeezing the case gets it to release.The slide out feature with two flat prongs is wonderful. I like that so much better than the single slide out piece on the NT 30 that my iPad mini case has. I find the iPad is much more stable when separated from the keyboard. Another handy feature is the little ledges that hold the iPad Air in place at the back of the keyboard when the stand is in the open position.I also really like the full size keys on the keyboard and find it to be very responsive and warms up very quickly.I wish that some kind of screen protection was included but it's easy enough to obtain a screen protector film to protect from scratches.Other than the need for screen protection, I can't really find anything about this case that I don't like. 

Question: What is the control grip material?
