I was three days in Paris, and after just three weeks on the Camino Frances go, everything super coped.
There are countless straps and loops to the outside to fix something, but I had two bungees this to securely attach my sleeping bag to seeing on the image to yellow loops. This may be a bit worn out, but had no problems with it.
The large tray can be opened down to it as to connect to the smaller zipper compartment at the bottom of the backpack - or a sock is twice I slipped in the other compartment holds but tight.
Reisverschlüße and buckles all act very robust, me is nothing cracked or broke, and I was not always timid. Still, I would not try with all my strength to close the compartments when became packed.
Hip and shoulder belts do their duty. I was about 11-14 kg of luggage on the way, back pain or the like I did not have. But can not really evaluate, I am not an expert for this.
The only shortcoming is the rain cover. This does not exist, because the backpack allegedly waterproof se. That may in rain or short showers are true, but I had to deal with snow and constant rain, and on two days my entire luggage was wet. If you have to expect rain and wet, so I still recommend to buy a raincoat, a good poncho should the problem but also solved.
Conclusion: Top backpack that almost everything Withstands. Would I buy again.
