I almost didn't take this on my trip to Italy, I thought it was too flimsy. but at the last minute, I realized I was going to need it as I couldn't fit everything into my carryon. Well, I was so glad to have it , light weight way to carry around jackets as the day got warm, nice inside zipper pocket for safety , nice zipper outside pocket for connivence. All day, as we bought souvenirs, into the backpack they went. It holds a lot. The zippers are tricky, make sure to zip both all the way over to one side or the other, then when you want to open it, zip both of them straight up, then open. Otherwise stuff can come falling out.
