I was really disappointed the rucksack - so I'll send it back: the "handles" on the zippers are simple string loops with rubber end, the aufrutschen repeatedly. Have you tried several times to tighten, but she continued to loosen massively. As a consequence, I immediately lost one, a second straight seen when falling. Otherwise, the backpack would have been ok. Many subjects. Thoughtfully. Whereby the PC compartment is slightly turned out very big.
