I have had this bag for about 5 years and I decided to write a review now because it feels like I bought it yesterday. Its quality cannot be compared to any other bag I had before. I use it daily for school, I always take it on trips whether by plane, car, or boat, and I even use it at the beach. It doesn't have a single sign of wear and tear.

In terms of technical aspects, I think you can see the compartments it has from videos on YouTube. I should mention that I put my 17-inch gaming laptop from MSI (msi ge73 raider rgb 8re if anyone wants to see the dimensions) in the bag and it fits fine, but not comfortably. I believe anything larger than that probably won't fit. The laptop compartment provides good protection, and I never transport it in any other way.

The zippers are of high quality and none of them have broken in all this time. It is quite waterproof, and I have never encountered any issues (although especially when I have the laptop, I always open an umbrella just to be safe).

The rest of the bag is very satisfactory for me, both in terms of space and compartments. It has two fixed compartments for water bottles. While it doesn't have mesh to hold the bottles more securely, they don't spill and they look nicer in my opinion. It can fit even a large bottle.

The glasses compartment is a huge advantage. I am someone who takes great care of my sunglasses and I never thought I would take them out without a case. But it offers such protection that I can't describe, you will understand and trust it easily when you see it.

Overall, in terms of space, I would say it is fine even for traveling. Maybe you can find a bag that can fit more clothes, but I don't think it would disappoint anyone, especially considering its quality. I believe you can comfortably pack clothes for at least 2 days.

In terms of comfort, it suits me 100%. The straps don't have much padding, but because they are wide, they have never bothered me. The padding on the back is very good. Generally, all the handles, straps, and padding are made in a way that will comfortably last you over a decade (and probably more). It also has a chest strap to secure it on your chest if you want to take it on a motorcycle, bicycle, or hiking. I have tried it several times and because it is adjustable in height and width, it is very convenient to carry it wherever you want.

In general, it has been 5 years and I haven't found another bag that I would want to replace it with in any price range (which is quite rare for me). It meets my needs in terms of practicality, durability, and I really like how it looks. And even if it were to break, I would still buy the same one.

I highly recommend it.

I have had the bag for about a week now. This is NOT my final review, just some initial impressions that I have formed.
The construction quality is excellent. You feel that this fabric will withstand any situation and any need you may have. It is sturdy, waterproof (within reasonable limits, I don't expect it to withstand a heavy storm, for that you may need a waterproof cover) and gives you the impression that it will last longer than its owner!
As for comfort, I had a few opportunities to use it, mainly for carrying my laptop and peripherals around the neighborhood, so I can't say much. In these short trips, however, it seemed very convenient.
Lastly, let's talk about the space. Here I can confidently say that it will satisfy anyone who purchases it. The laptop compartment adequately protects my computer, while it also has a pocket for a tablet, which comfortably fits my 12.2-inch tablet WITH its case. I'm not sure if it can accommodate a larger iPad Pro, though. It also has a wide pocket for documents (clap clap). The main compartment is spacious, and there are two small pockets on the top that are convenient for storing items like mice, earphones, or a power bank. The front organizational compartment has more compartments, zippers, or whatever else I need. It easily fits my oversized laptop charger, and all the cables, chargers, or accessories I have fit nicely here and there. It also has an attachment for glasses with a hard case, which I found particularly useful. It also includes a pocket for a mobile phone, which is probably intended for a 4-inch iPhone rather than anything else. All this glasses and mobile phone package secures with a loop, which, although it securely locks the attachment, requires a little effort to "lock," so I do not recommend putting your belongings in this attachment if you plan to use them in a short period of time or if you want quick access to them. This attachment takes up space from the main compartment, but the bag is tall enough that you won't miss the space. Finally, I like that there is an open pocket in the front for things-I-don't-know-where-to-put-and-I'm-not-afraid-they'll-be-stolen, and two pockets for water bottles.
At the end, I have a URL for the bag presentation video so you can see what I'm talking about in action (although they have changed the zipper design, hence the difficulty in securing the glasses attachment). The bag is definitely expensive, but as I said before, it is of very high quality and has a good chance of outlasting its owner. Also, the bag's actual name is Thule Crossover 32lt Daypack, and I don't know why the stores, and subsequently Skroutz, adopt a different name.

Update 23/1/2018________________________________________

I had a busy semester and had the opportunity to test the bag in several areas. From going up and down the school, to carrying my laptop around the neighborhood, the bag has fully satisfied me!

As for comfort, the predictions in my preview were correct. The bag is really very convenient! I had several doubts about the bag straps, which do not have any padding but are made of a spongy material, but I was worried for no reason. The bag is very comfortable on the back, without causing much fatigue. One concern that was confirmed was the richness of the padding on the back of the bag. While it makes it very convenient during winter, in the summer (and generally on hot days) it heats up the back too much, resulting in... not a very nice aesthetic result.
Its durability is remarkable. With 5 heavy textbooks in the main compartment, and the ordeal it went through on the bus and after some other minor accidents I had on the road, I am sure that the bag is armored!!
The daily load of the bag is not particularly heavy. In fact, it is nothing more than a tablet, a power bank, and other cables and such. For this reason, I really recommend someone to have the intention of utilizing a larger part of the bag than I do. Otherwise, the bag becomes somewhat empty.
The only thing I haven't tried yet is using it as a travel bag, which will probably happen within the next month. I will upload an additional update then with my experience. For now, though, the bag deserves its 5 stars!

Update 6/9/2022________________________________________

Hello after the pandemic.
The bag has been on trips, carried a whole bunch of stuff for vacations, carried a laptop with a cooling pad, charger, and other gadgets, been through the washing machine multiple times, and it's all good.
I truly believe that I will die first before this bag does. I am completely satisfied with its functionality and quality. Maybe its appearance doesn't hold up as well (the net that connects the open front pocket with the rest of the bag creates an unpleasant contrast with the otherwise beautiful weave) but it's not something that ruins the experience at all.
Of course, with the price fluctuations it has, whether it's worth the purchase depends on how much it costs at the given moment (or how easily one can find it even in the used market - it holds its value well). Especially for over 100€, there are many other good options available.
However, if you get this bag, I doubt you will have any complaints.
