This bag is great to be your personal item when traveling. It has a nice front compartment where you can place anything from items you want to easily reach. The inside compartment fits a laptop or iPad or both which I did on a recent trip. There is a suitcase trolley pass through on the other side with a side pocket which I used for my cell phone and passport. This fit under the seat during recent trips. The outside is nylon so anything can be wiped off. This bag is a 7 1/2 inches deep and 20 inches wide.
