What the description does not tell you is that the laptop pocket is smaller than the bag dimensions and will not take a 15.5" wide screen laptop (even though the bag will). Laptop pocket is roughly 2 inches narrower than the bag width and not as deep - probably take a 14" laptop. For a messenger style laptop bag you can find better and cheaper options on Amazon from Belkin and Computer Gear.
This bag is quite big and of reasonable quality. Fairly non descript to look at. If you are looking just for a laptop bag then this is probably too big unless you want to carry an awful lot of other stuff as well.
This bag is a cheap flimsy piece of crap. The material is very thin and the shoulder strap pad tore after only a few uses. Wouldn't recommend for regular use or for carrying items that require any degree of protection. Normally Head are quite good for stuff like this. Naughty Head.
Okay for the money, but more flimsy that I thought. Could do with a bit more padding. Thought I could use it as an everyday bag, but it looks a bit cheap. Using it to store spare laptop & drive and perfectly fine for that.
