The bag looks more compact than the real image. I'm not surprised we can use it with a 17-inch and fortunately I am not allowed myself to order one size up! for my part I managed to insert my laptop with a 15'6 fan provided for models from 15 to 17 inches. There are A lot of compartments for storing accessories or folders. The wide shoulder strap allows the transport with comfort. In short a purchase for me that I do not regret.
