I bought this bag after I saw a lady on vacation with one. (I got the 16" satchel tote.) And I love it. It's SUPER light - but sturdy which is not a common combo these days. The zipper goes almost all the way down the sides - great for getting large things in and out. (I use this as a carry-on to hold all of my medications/supplies, book, water bottle, sweater, etc. You can fit a lot in it!) As another reviewer said, you can't really wear it on your shoulder (unless it's not very full and/or you have tiny arms), but it's so light that it is fine on the forearm, or even in hand. I love it, and it goes/will go on all trips with me. I even started using it to carry around my work stuff during the week. Highly recommend.
