Matein backpack- great for high school and travel

I bought this backpack for my 14yo son. He uses it for school and to travel. It's quite sturdy and water resistant (it was raining yesterday and everything was dry in the bag when my son walked back from school - 15/20' ish).
There's a USB charging port, which I don't really care, but it seems amaaazing (believe my son...). More important (believe me^^), there's an anti theft pocket, where he can place his cash and passport when walking in shopping centers or travelling.
This bag can definitely be used by adults as well. I recommend it, good quality for the price.
