Who is frequently traveling by plane and want to do without large luggage is well advised with this backpack. He is surprisingly spacious, acts processed stable and can be worn halfway comfortable. The comfort here is not with eg a Deuter backpack with carrying system comparable, but is totally going for the intended use in order. Laptop, "electronic accessories" cosmetic bag, change of clothes for two days and even a sweater - not a problem as there is still enough space. I rather suspect, also a holiday week, the storage capacity would be sufficient for me.
Appreciate really learn the advantages of a backpack against a trolley or a bag by the way at the latest when you still have to walk more than 1km to the gate at the airport.
For price-performance perspective, therefore, a clear recommendation.
