Positives:
-Very well made
-ziemlich rainproof
padded -angenehm
-Beautifully large front compartment
-Optimal size if you need only laptop, block, wallet and maybe a book.
Negatives:
-For MacBook Retina 13 "something big (probably even fit 15" still almost purely)
-The Storage space of the main compartment is limited by the fact that the pack toward the front slightly tapered, could be a bit bigger for my taste
-has one in every bottle compartment, on the sides, each a 0.5L bottle in it, partly unstable folders or books push up inside something, because the elastics of bottle compartments are quite tight
-kippt slightly forward to because the front tray is not set at the level of the soil
Overall a very good backpack, if you do not need so many books. Much Collegeblock (160Seiten), 1-2 Folders and a thick book (about 500 pages) and a slim pencil case in the main compartment can hold (yet) well. Everything that goes beyond that is a bit short.
The front compartment is divided generous and useful.
The processing of the backpack is very good. Since the belt beyond the zipper laptop compartment addition, one can not be stolen the laptop also in the crowd at the station. You have to settle the backpack and the straps do something aside to get out the laptop. I like it!
