Bought this specifically to fit a 17 inch laptop and allow room for files and supplies. Pleased with the capacity - it meets the need. Only issue with it (a minor one) is that it is a bit top heavy, making it harder to stand - but feel that will be resolved when there are more files/clothing in the larger pockets. Unclear on water resistance, which is why I gave that 3 stars - generally I don't submit laptops/bags to any water/rain if at all possible. Overall a solid laptop bag for bigger laptops with enough room to carry laptop and files. Warning - when fully packed, it will be heavy.
