It's a good backpack. Quality, well designed and well distributed. Two things strike me: firstly, how comfortable it is (and it's not the first urban backpack I've had) and secondly, despite the fact that it's very sensible, its capacity is excellent. I usually carry all my things in cardboard boxes, in metal or plastic boxes so that they don't get scattered around me, and the truth is, I was very surprised: when I received it and saw it for the first time, I didn't think so it would fit whatever I put in it and there's still room left. And all of this without the backpack deforming or losing its design. I walk around the city a lot - and I take a cane with me because I have difficulty walking - and the truth is that my backpack doesn't bother me or weigh me down. When it comes to security... Well, the little thing with the numerical code lock is very good, but the backpack cannot withstand the "knife" that criminals in Barcelona (Spain) are so fond of. However, backpacks that can withstand this are much more expensive and pay more attention to durability than to interior and exterior design: I prefer this one and take the risk. The front pocket is very useful for carrying the inevitable papers that you end up having to carry with you no matter how digital you want to live. It's nice to be able to access it without having to open the backpack and crawl inside. The fact that it can be separated from the set may be funny, but it doesn't make me feel cold or hot. In the months I've carried my backpack I haven't unplugged it and I don't think I will, except perhaps on a very sporadic occasion. In short, a highly recommended product with good value for money. There are of course much better backpacks (and beware that it's difficult), but if you want them, prepare your wallet.
