If you're looking for a durable standing case for your iPad, the Incipio Kickstand case may be for you. It is made of rip-stop nylon on the outside and lined with microsuede on the inside.
The Incipio Kickstand is designed with different panels so that they can fold into a triangle, converting the case to stand. Since the inside is made out of microsuede, it has plenty of friction to keep the iPad standing without special notches, hooks, or flaps to keep it in place. Unfortunately, there is only one angle you have the iPad stand at. This fixed angle keeps the iPad standing tall, perfect for setting on a desk and watching movies. If using the iPad on your lap, you will not want to have it set up as kickstand because the angle is too awkward.
Not only is the microsuede great for providing necessary friction, but it's also very soft and at no risk of scratching your precious iPad. Also, the inside of the middle panel has a pocket that is great for holding items such as envelopes, notes, and business cards. Lastly, the Incipio Kickstand has a magnetic closure which allows it to be free of flaps or fancy closures.
The Incipio Kickstand for iPad is available in the TiPb iPad accessory store in three colors: black, light gray, and khaki/tan. If you're looking for a nice standing case that also offers some good protection, I recommending checking this one out.
