It would be pretty difficult to lose your stuff when you’ve got something with this many compartments.  Plus, it has an anti-theft zipper, a waterproof pocket, *and* a shoe bag!

Promising review: “One bag handled a week of travel! This bag is like magic! I fit four pairs of shorts, four shirts, underwear, socks, and a couple of workout outfits with sports bras, two pairs of sandals, four bathing suits, a coverup, a sun hat, toiletries, cosmetics, a laptop, a notebook, three device chargers (computer, phone, and Fitbit) and an electric toothbrush. Even when packed to the max, the weight is comfortably distributed so it doesn’t break your back. It fits under the seat perfectly, too. I bought it when it was 50% off, but I’d pay full price knowing how awesome this bag is for travel.” —AlexanderK
