Excellent quality, this is the 30 liter one, it doesn't look huge on the back and it's comfortable, it has enough space, it's intended for travel, I went with a light color because the previous black one from the same company faded in the first 2 years, the color turned and became brown, it got to the point where it was unsightly after 3 years! But maybe they have improved their materials in these new backpacks

The best backpack I have ever had. It is quite large, exactly as I needed: for university, for laptop and books, even as a personal item at the airport (without being completely stuffed). I use it every day and it is perfect.
The downside is that after 1.5 years of use, the leather straps where you adjust the size have started to crack and are almost ready to break. I don't think this is normal, especially for the price it had.
