The backpack fulfills clearly his mission, he has many fans and good adjustment. However, the substance, compared to other products is not very thick. But that remains within the value framework, unfortunately sold Amazon backpack for just under 100 euros, although in the description of the manufacturer (also on the Amazon page) an EIA is of 79,95, or stand. After recalling Amazon took this EIA from the description. These were by no mistake as Amazon France also this price proposal is presented. Therefore my conclusion, for 80 euros, this backpack fine but more I would not spend it!
