A small drawback is the stability. The bag tends sometimes to tilt forward.
But for me, it's to get away with a lot of great voyages.
Air travel is not a problem, the material is durable and can put away a lot.
What I like best is the division into 2 different majors that you can open virtually.
For a round trip so I could separate clean of unused linen.
In short, I'm excited and very happy to give a buy recommendation
