I use the bag for mehrtägigige trips during major tours. The bag is then folded once transported in the trunk, on the spot I pack some things around in the Aerolite. The bag is low odor, very light and can be again with no real problems to fold small. To date, it has held up well, but I'm also careful to her. Have to give up as baggage they can not - that's your hand luggage! Hook: Due to their ease the bag has no "fixed structure". If we make it not full, so it deforms and the content is jumbled wild. Even the packaging is a little more complicated, because you always have to stop the bag with one hand.
