Took these to Europe for two weeks and they endured planes, trains, and cobblestone streets. They held up well. They're pretty roomy and you can fit a lot into them but I do wish that both sides had the mesh zipper closure to keep things in place. When you open it you want to have the mesh panel on top because the other side has only an elastic strap to keep things in place. Unfortunately, I could never figure out a way to determine which side was which just by looking at the outside of the bag so every time I opened it, it was a gamble on whether or not half of my clothing would fall out. But other than that, these are nice bags. I got the teal color and it's really a lovely color. You can't tell from the website but it's like an iridescent color not unlike a bottle fly.
