The bag looks really nice, is virtually built and relatively easy. Unfortunately, the external dimensions just slightly above what most airlines allow as free baggage - length + width + depth 158cm - here according to the manufacturer 160/161. By ground leaf and the rails can be down and not do anything. Ie take the risk that your luggage is not transported or you high fees will apply if someone measures. This really is extremely unfortunate. I would have liked such a model with 120 liters that still fits into Airlinemaß without that I have to sweat at the airport. Do not quite understand why such a thing is not taken into account in the design. The next smaller size of IQ are then only 100 liters. Too bad, because otherwise it's a nice part. This detail has so annoyed that I had to forgive 2 stars.
