Sturdy construction with quality materials, it is very compact, lightweight, and convenient. It holds many things, clothes, small items, a laptop, has pockets for various items, a USB pocket for charging the phone. Shoe compartment. If not full, it fits under the seat (airplane) and is considered a personal item. Capacity 40lt. It is perfect for short trips and for those who travel frequently.

Large, lightweight, comfortable, and with enough space for laptops, clothes, and items one might need for work or travel.

Quite sturdy construction, it is quite large both in volume and in appearance. I have some doubts whether the airlines will accept it as a "personal item" that must fit under the seat. I think if you don't have it completely full it will be okay
