As a material, it is very good; the only problem I see is that it doesn't have many compartments to put various things in, while it has a large bag, let's say it doesn't have enough pockets to separate things, and another thing it lacks is that the computer doesn't have a good cushion underneath and it hits the ground when you set it down abruptly.

It is not very comfortable on the back and it is not spacious, several pockets but small, it has not been tested yet for how waterproof it is.

Absolutely excellent, well-crafted bag. Truly waterproof, spacious, and easy to carry. It comfortably fits the laptop, its charger, an umbrella, a thermos, a headset, and food, and there are definitely pockets that I haven't explored yet.
