Note: The felt is not fluffy and soft and a little lighter than in the picture, fear Kraztern did not but I, unlike some other other Sleeves Softshell / neoprene materials that I no longer use. The felt is relatively thick, so that it protects the MBP also good. Drop it, I would not yet;)
Please note the following:
the felt is folded over and sewn together at the edge. This makes the whole a good deal (1.5 / 2 cm per side) is wider. I select a narrow Grumpler 15.4 "MBP bag, the Sleeve it fits no longer well into it. Maybe a little less tight pocket.
I still give full marks, I like it simple and is reasonably priced.
