I travel extensively and needed a backpack that would provide durability and roominess. I have an Alienware m17x-R4 17.3 laptop. There is absolutely no problems with fit even using a protective sleeve on the pc. Storage pockets abound! All of my stuff fits in this backpack and it looks great. The only drawback I see is the front pocket. The stretchy material should be more heavy duty in my opinion. I was carrying a thermal mug and bottle of water in it but now there is a small rub hole and a couple of snags after less than a month's use. A little disappointed on only this one issue. It should only be used for small objects like a Reader or iPad where the material is not stressed. Otherwise, this backpack suits all of my needs.
