Contrary to my fears, the bag is not to just cut to 17.3 ". My Schenker Notebook, which far thicker than the average but, fits in with no problems and there is still plenty of room for additional accessories. For whom the only every now and then with the Laptop runs on a LAN it is safe enough. But I have very intense and well filled him used (3 evening classes per week), and here I have to complain about the after 1.5 months starts at the seam right carrier to be working slowly. Too bad because otherwise it would be a real good backpack with many compartments and plenty of storage space.
