Got this bag for the wife so she can use it while she travels. It's made of a tough nylon type material and has withstood allot of digging into and tossing around by our great TSA agents. The bag is a perfect size for a carry on. She also uses it when we go on trips, like when we went to the Zoo, and she carried her camera and other needed items in it. She loves this bag, and I have plans to get my sister one as well.
