The HAMA Notebook bag is not bulky and particularly taking my 17 inch notebook with a larger battery for future reference. It served its purpose perfectly. A "bead" behind the zipper prevents accidental scratches by the zipper. The sleeve has a patch pocket for accessories. The material used therefor is stretchable enough to accommodate mouse or power supply. The protective material of the actual notebook case seems strong enough to cushion any pressure parts in the front pocket on the notebook. However, the case loses then of course her slender figure.
I use the cover to transport my laptop in a pocket, in your backpack or suitcase. In order solely to transport the notebook in which I'd wünchen a less slippery outer fabric or a handle to secure.
