Very fine lightweight bag, in the place the Ultrabook very good place. Unfortunately, battery and mouse no longer fit in the bag's really only meant to protect your notebook. For the price it is sufficiently well-made. The tab and the protection at the bottom, however, are very reasonable Kunsstoff because I would have been happy about leather or the like.
Basically, the bag is practical and stylish. I like it well and I'm glad that my Ultrabook actually purely fit easily.
