Who buys a Cosmolite need to know that these cases are designed to consistently low weight with high stability, great interiors one must not expect so. Who is the weight advantage at high quality is more important who gets a Super suitcase! For me that's the case, the case met my expectations in terms fully. In the cabin trolley is much more important, so I use also for the Cosmolite- or Cubelite series.
The only downside is that it is about 10 cm above the allowed when boarding. Flights totaling 158cm. When the wheels do not mitmisst he is just under it, besides, I've never heard of dimensional checks at check.
Nevertheless, if an airline wants to make problems she has good cards in the suitcase. I wonder if it times to clock-in for this uncertainty I subtract one point.
