Good travel bag - were it not for the dead weight

Got the bag in front of a 10-day holiday ordered to have enough space for my clothes and the odd souvenir. Since I'm not a big Kofferfan, but did not want to give up the luxury of the rollers, my decision has been made on this TT-pocket. In addition to the roles, this bag that is also still possible to wear it with the supplied straps as a backpack.

Positives:
+ Innumerable small pockets
+ Roles
+ Material Quality
+ Size / shape stability

Negatives:
- Heavy weight
- To wear uncomfortable
- Size / shape stability

The bag matches when empty unfortunately already over 6kg on the scale, which at the current free baggage allowance policies of airlines often allow only one additional filling with about 14-17kg. Amazingly, this payload weight is nevertheless achieved quite quickly and then the bag is often not even 3/4 full. Among them will harm the natural shape of the bag, so that it was as wide sideways at me at the airport I had problems to put them right on the luggage belt. But you have to make allowances for that, there is also the possibility inside to tie down the content so that it can not slip as in duffel bags. Filled the bag is so inherently stable that they can be worn comfortably and roll.
