The Belkin Portfolio Sleeve is particularly suitable for storing and transporting the iPad mini. The device fits into it perfectly and is enclosed so that there is not sliding around in it, and is protected against bumps and scratches. It even fits into it yet with the Smart Cover. The two zippers are smooth and the iPad can be seen well.
The material (neoprene) is insensitive and very easy, however, to be recommended in this case just for surfing the Internet while ;-) There are no washing instructions exist, but normally the case would have to be washed by hand, if you should be times angeschmuddelt.
I like it for transport or when used with the Smart Cover as a protective cover very good, but otherwise I prefer cases that are solid and have a positioning function.
