Really great, but not overly tough

I need large backpacks that can carry heavy and must be durable. My last Deuter I had 7 years (and still have not sorted out him, though he is now completely riddled) and I wear my backpacks min. 5 days a week.
In this it is that he really is the only on the size of my old Deuter zoom comes (a large main compartment and plenty of storage space for odds and ends), but he does by no means as a stable impression. The outer wall thickness and the material seems more like that of a 20-pack off the shelf, even if the processing is certainly better. Also we see no water-repellent layer inside. (Impregnating!) The rear panel is for the back a catastrophe, it is completely flat. Since I have sweated in March at 15 ° ambient temperature on the back. Airflow is zero.

I am reasonably satisfied with the backpack and who has similar requirements like me and can not find another one I can recommend this model also. Deuter Backpacks would still build the size of my old, I would not hesitate to take a Deuter.
