Durable and very good from spaces. The zippers are among the strongest I have encountered. It becomes very compact as it folds to store it. The only slight disadvantage is that the strap rings may open under very rough pulling.

Value for money. The only downside is the clips that the shoulder strap attaches to, if you replace them with something sturdier (I put two carabiners from an art supply store for 0.40 cents) then it goes wherever you want! Comfortable, spacious, and convenient pockets. I bought two and have already used them on multi-day vacations.

Of mediocre quality, if you fill it up, it starts to collapse, especially the side rings start to open.
