Unfortunately, my 17 "(MSI Stealth Pro) will fit AT ALL This is certainly a very good bag and it's class but he does not really seem to have been designed for computers.. I have the impression of have a hand between the (very good) hiking bag which we added protection for computer Indeed. Just in front of the part dedicated to the computer, there are ... A zipper! Basically if you have a 15 "this bag is definitely ideal for your notebook will return in full within the protected compartment (I can send pictures if needed). But a 17" above and is then against a zipper. In my case, I can not even close the bag (it's a 17 "16: 9 --- ditto, I made a picture: it is obvious, like the top of the bag is rounded the corners of the PCs are out of the bag, one side can be closed by forcing but not the other) which makes it unusable.
In summary, this is a great product but unsuitable for portable 17 ". So I would like to say to merchants to update the product and sell it only for 15".
