Ditto functionality - is the highlight side carrying handle, which is not self-evident in this size even with expensive manufacturers. The compression belt, the thickness can be reduced, if necessary In what budget airlines with absurd demands help to the size of cabin baggage.
The color (Blue To Or Not To Blue) you have to like, I think that's great (slight tinge turquoise). Under no circumstances a neon hue.
A downside is the weight of 2,13kg for the model Tranverz XS (name of Eastpak) in for example 10kg free baggage in my opinion a bit much. Here the product description with indication of 1.6kg Amazon is definitely wrong, a smaller and lighter version so there is not even mW. Nevertheless, I would take him by virtue of such advantages and durability again - If you're planning a Neukaufen actually becomes necessary.
