Not too sure how to buy a backpack on line, and it showed when I got this delivered. Yes, it worked for my needs, but don't judge the size by a picture on line. It will be smaller in real life. Not much room for what I needed, that's on me for not knowing. Photo was mis-leading. Decent material but a little extras would be nice. Like a strap to go around your waist to help keep it secure. The photo shows a strap that looks like it will do that, but it's only for tightening the shoulder straps.
