Have your backpack since yesterday and am now so walking through the rain. First of all, the backpack is pretty easy! I appreciate seeehr because I previously had a rather heavy backpack which had annoyed me really. For light weight also comes still a super comfort. The carrier belts are fairly broad, well padded and ideal cut. The AeroFlow back padding also contributes their part to the comfort. The jerk does not sweat and the backpack is very soft padded. The Notebook compartment is for my notebook (15.6-inch 16: 9 aspect ratio) optimally in terms of size. Merely the belt for securing Velcro is a bit too short. But does not bother me, because the notebook sits sufficiently stable. The notebook is all padded out above. So who's up to a handstand with the backpack close to let him then fall who has a problem. Seriously, it could be problematic for some, that the notebook compartment Notebook not completely covered. From the main compartment of the backpack could in this way so fluid or else enter the notebook compartment. Well I will hardly happen. For the upholstery must be said that it is rather thin. To me she goes but. The material is absolutely rain hard. Am today running through the rain ... However, pockets on sides in which it may enter rain. If it is really time right Doll rains, I can imagine that there dammed water and then can flow into the other compartments. I find the design very well. The only serious drawback in my opinion is the quality. The fabric is great, but the quality and especially the position of the seams is better or worse, cause they will go up after some time. The same applies to the AeroFlow padding on the back. It remains to be seen when the backpack will begin to "dissolve". I'm definitely fully satisfied because I still expect that the backpack will hold a number of years. That's enough for me absolutely considering the price. Therefore 4/5 stars!

Addendum: I have to correct my rating dramatically down unfortunately. Only now I noticed that the corners of the notebook Facks are not at all padded. Afgrund this design flaw a corner plastic is broken off at my notebook !!! Very bad! Luckily, I get the money back for the laptop because of another defect anyway. Otherwise, I'd probably be annoyed about the extremely Kontruktionsfehler ...
