This review is intended to serve as a decision support for the right size: Why this bag: I need this cover as transport protection in a backpack, in the often roll around other parts, before this, the notebook should be protected without applying too thick. Since I took the bag in the "normal" fit for several years for my Acer 1810 which has perfectly fit well, have something similar for the Thinkpad X240 from Lenovo ago, actually a 12.5 "-Subnotebook. The 11.6 "bag with" larger size "fits really perfect for this device. The corners of the laptop are well protected from the zipper by an internal fold, and the patch compartment offers plenty of room as needed for the power supply and a small mouse. Other: Packing Because you saw initially a few footprints on Neopronmaterial, these have disappeared. Quality zippers seem to be very good, smooth - In sum, considering the price clear 5 Stars.
