This bag was purchased for a budding Africa trip and will be back-tested in summer. The first evaluation was so far very good. The surface material appears of good quality, also the seams. The zippers can be drawn easily. The subdivisions tell me too well and I hope that the practical test will also be positive. The adjustable strap system appealed to me from the beginning, because I had to buy any additional straps me. At the skate wheels I'm still excited when the bag is fully packed on uneven ground. You definitely see from very stable and stress-resistant.
