Tremendous quality and meticulously designed construction. The hard case fits perfectly wireless headphones like PCX550 & Sony XM-3. On the back, a 14-inch laptop fits comfortably, and in the front pocket, it can fit a surface along with a keyboard (simultaneously with the laptop). The main compartment has very practical pockets, and the volume can be adjusted with the straps at the bottom. The bag is not poorly made; it is evident to anyone who sees it up close. It even has a soft material on the handle to prevent hand pain when carrying it.
I am around 1.74 meters tall, and I don't think it looks so big unless someone is used to smaller polo-type bags. If you can find it, get it, it's worth every penny.

I bought the bag and have been using it intensively for the past semester.

Whether for school or for grocery shopping, the bag fully meets the needs it is intended to cover. It is well-made with durable materials, sturdy, and quite spacious in size and volume even when empty. It provides both specialized compartments and general-use pockets. For example, in the iPad compartment, you can place a folder or a slim notebook. It has a net capacity of 28.5 liters.

What others have mentioned, that it appears huge on individuals under 1.80m, is true. A more detailed review will be provided after one year of use!

Update: I even went on a 3-day trip and had to fit a GoPro case, a DSLR case (as an adventure enthusiast), 2 changes of clothes (underwear, pants, short-sleeve shirt, socks), and the essentials for the first day: 1 water bottle and 2 large sandwiches. IT FIT THEM ALL! Simply unbelievable...

Update 28/5/2023: For the current price, it's not worth it. I bought it for 88 euros and it was okay for that price. But 140 euros for a bag that will have its zippers break after 3 years of daily use? There are definitely other reputable options available for that price! It's definitely not worth more than 100 euros. Look for newer models from the same brand or other brands.

Excellent quality and durability. It fits everything even though it looks a little huge. Very comfortable on the back.

Good quality, plenty of space, and the hard case for glasses is very useful for trips, etc. It's worth its money, around 90 euros. Just to be comfortable, the large (28 l) one needs to be over 1.80 meters tall so it doesn't look enormous...
