inches for the 17 laptop is made, with additional compartments and features. I use the main compartment for travel with 1-2 nights. you get out the laptop with accessories and a few files even the clothes and utensils for a short stay pure. the bag expands enormously, without losing the shape. The price is fully in order. I have on my trips now just a bag here without wheels, and ironing, which are annoying when stowing again and add weight. but with shoulder strap. The only drawback: I would have liked to have had something to lock the zippers. still 5 stars.
