+ Great size
+ Super camera compartment
My 15.6 inch laptop just fits rein..der zipper still has enough room, so I've been lucky again. I do not know the dimensions of the head, but later they will supply later time and possibly even take a picture.
In my opinion, the main zipper had something can be solved differently, because the opening is almost a little tight, but it also works like this!
Especially great I think as I said the camera compartment, which can be pushed by means of a belt to the side ", leaving you enough for everyday wear, when time is no camera with me, a full backpack :)
EDIT: Have now uploaded an image as the backpack with my 15.6 "laptop looks.
But as I said fits easily, got the picture and little commented
So have fun with the bag =)
