I bought it solely for professional use. I am a civil engineer and I always carry a laser, a measuring tape, a folder with drawings, 2 13" laptops, an A4 folder, an agenda, and sometimes money.

Negatives: In the second week, it started losing its shape, meaning it has some creases and it seems that soon it will completely lose its elegant shape and turn into a mess. The outer fabric slips compared to the hard interior, and you can see that the seams are no longer in the corners. It is also lacking a pen holder. I don't know how long the internal compartments will last before they wear out.

Positives: It is very durable on the back and looks elegant at first glance. It has plenty of space for me to carry my office with me. Even with the things I described above, the bag is not full. The hidden pockets in various places are very convenient for wallets, money, or credit cards. It has special compartments that block the magnetism of cards so that no one can steal their code.

In conclusion, they sell design and security, but they have lost the basic elements of quality, and I consider it excessively expensive for what it offers. However, I don't know if there is a competitor in this category and at this price.

Update 3 years later...
The initial impression was with 3 stars.
I'm giving it 5 stars because it has proven to be very durable. It hasn't lost its shape. The only thing that has lost its shape is the front straps, which have twisted a bit and don't sit well.
The biggest negative is the lack of a pen holder...

Very convenient backpack for professional use, lightweight, with smart design and plenty of storage space.

I had a replica of this bag style for 20 euros. Well, the authentic one is nothing like it! It's 100 times better, and if you're like me, who carries a backpack every day due to work and have concerns about the safety of its contents, it's definitely worth investing the money and buying it. It's exactly as advertised in every way. I will buy it again if the one I got breaks.
