Suitable backpack/suitcase for small items, a 17" laptop, items that are best placed in discreet compartments, for about 10 pieces of clothing (only if the backpack is expanded), for adverse weather conditions (rain), even for... a standard-size backgammon board (48 cm long)! The material used is top-notch (1680D polyester), which keeps its shape despite the weight. Besides blue, it comes in 3 other colors. The only warning: the backpack, when full, becomes very heavy, without this meaning that it cannot be lifted. I am more than satisfied.

Ha, what 17.3 they say, 18.5 portable monitor with its case fits easily.
Huge space, and it seems to be durable

I have worn out this backpack over the last 3 years on business trips using it as a personal item on flights (placing it under the seat). It has been through heat, rain, and all my belongings were protected. I even experienced an accident with a water bottle in the middle compartment that broke due to pressure and the water spilled downwards, but it did NOT reach the laptop section. I also bought the backpack in its larger version to have it for my travels. I don't have enough good things to say.

The bag has a lot of space. At the very least, it's ideal for anyone carrying a laptop, etc. It is also waterproof up to a certain point. For heavy rain, it needs a waterproof cover because water gets in through the zippers, but that's reasonable

Quite nice bag with many compartments. You need to get used to it because you open the wrong pocket. It seems to be quite durable, time will tell

Relatively good bag for traveling, large capacity, comfortably fits 3-4 changes of clothes, shoes, accessories, etc. The zippers are good but make noise. It opens from multiple sides for different uses, which is both good and bad. You need to get used to it, otherwise you'll keep opening the wrong compartment.

As for the very negative aspects, the laptop protection is very mediocre, I wouldn't put it in without something extra inside.

Also, as a negative, the price in Greece is high. I recently bought it while passing through China, 158 yuan (about 20 euros) directly from the manufacturer's eshop. It is definitely worth it for that price, but it is NOT a 70 euro bag! Ridiculous.

It looks like a very good bag. It has very good adaptability in size when it is loaded or not. For everything else, I will come back in a little while to have a comprehensive opinion after some time.

It looks very high quality, of course, time will show its durability... It has a lot of space, especially when you open the middle part, it's like having a cabin suitcase on your back. I bought it because I travel with a motorcycle, of course, if you have a passenger, it doesn't fit because it's quite big... I got caught in a rain while riding the motorcycle at 80-100 km/h with moderate rain, and no water passed through, so the waterproofing is good... I would say the price is a bit steep, but it's one of those cases where you pay and you get, and I believe it's worth it because besides traveling, I also use it daily for my laptop and accessories, and it's very practical..

I used it on a trip abroad and I have to say that it is ideal for a short trip. I bought it mainly as a carry-on luggage for such occasions, but obviously its use is not limited only there. It has many compartments of different sizes, and it is ideal for carrying a laptop if you want. It is waterproof, I tested it in light rain, but judging from its construction quality, I believe it will not have a problem even with heavy rain for a few minutes. The price is steep, but I recommend it.
