The workmanship is good and robust.Ich miss more compartments in the main compartment, and small external pocket, so smaller portions not in the large compartment verschwinden.Weiter I miss hanging straps on the side Außennetzen.Lange parts eg collapsible umbrella or water bottle can slip out of the net. comfort is very good, more grip loops at times briefly a windbreaker or sweater would flow to bring the outside also very helpful.
