# The backpack is very large, but just not too huge to act like a sack on his back. It can be by opening a wrap-around zipper still expanding (he becomes more deeply), so to get to the specified size in liters. The expansion option I've noticed even after the purchase. In fact, this is very convenient, because it makes the pack more versatile.
# The shape of the rucksack is not so square and not quite as deep as some other models, but rather high. No one uses the aforementioned extension of the depth of the backpack, so the weight is better at the back as in the box-shaped and deep models.
# The backpack has a large main compartment and a 17 "-Notebookfach, and various smaller pockets in front and on the sides. The notebook compartment course one does not necessarily have a notebook to use (I usually pack magazines / paper grade). The notebook compartment is extremely narrow and is increased significantly by opening the above-mentioned extension.
# The backpack has a firm grip and no tape. The handle is practical, durable and of good quality.
# The backpack has a right floor in the main compartment, but which you can fold either. This can be drawn even flatter through the side straps of the backpack when needed.
# The weight for the size and functions mentioned above definitely in order. The backpack is heavier than one would suspect. The soil is also very easy and brings no significant weight penalty.
# The outer material is very robust, the zippers seem well made. Although I had this also expects the price, however it seems to me (at least the offer price) but very low for the quality.
# I have the blue version (navy). In the real backpack sees my impression from after even better than the pictures.
The only thing I've found so far to criticize the carrier policy. While these are probably robust, but except for the additional connection tape otherwise made than with smaller and very simple backpack models. The comfort, however, is in order.
