The Zippelin isn’t for everyone, I’ll admit. For instance, I wouldn’t buy it because, at 85 liters (5,200 cubic inches), it’s just too damn big for me. Whenever I go on a trip, I limit myself to one medium-sized duffel and a backpack. What doesn’t fit in there, doesn’t get to go on the trip. If you enjoy the sturdy walls of some rolling suitcases, you’re also not going to like the Freitag. It’s stiff enough to roll around, but the tarp shell, however sturdy, is still soft. Finally, those lugging business suits around might be worried about the rubber smell. I don’t think bankers on business trips are Freitag’s target customer, though.
