40×30×20 Cabin Backpack – Airline Approved Underseat Travel Bag Compatible with Wizz air and Ryanair

Very large backpack, obviously if you use all the space at the back you can't use the part where you put shoes, but it has plenty of compartments, the material seems good.

Great, it arrived in perfect condition and I would buy it again, 100% recommended for traveling.

The bag is good, made of high-quality material. It is relatively small and can hold clothes for one day.

It's very good, it's quite large and holds many things. I've already ordered another one. I highly recommend it.

Good size and materials, the measurement corresponds to what was indicated! The supplier delivered in the rain and it is waterproof. The material is like nylon and the drops are not absorbed by the fabric. It surprised me for the better! The only thing I could say is that the inner lid is not exactly the same as in the photo; it has only 2 pockets instead of 4, but it works just fine.
