For this bag I can give a strong buy recommendation. I am very happy with the bag. It fits a 17 "notebook / laptop as well as just a" 15-inch "and if necessary, both in the pocket. An A4 folder is also not a problem. The bag is very spacious and very well made. The only drawback is when people with small hands to carry the bag by the handle when it is as fully loaded. But it is supposed to replace any travel bag.
