I cannot say enough about this bag. For a recent trip to Mexico, we could only carry 30 lbs. with us due to being on a small plane for transport. Plus we had to carry all of our own luggage ourselves. We were able to fit so much into this bag, then put it on our backs to carry, which left us hands-free to maneuver getting in and out of boats and climbing on rocks. The inside is fairly roomy. There are several zippered pockets, one end is specially built for carrying shoes, and there is an extra fairly nice sized bag that you can attach on top of the main bag! This is not a full-sized suitcase, so keep in mind that you can't take all the clothes you want plus the kitchen sink. However, for trips where you are happy wearing some of the clothes several times, this is your bag. The material is light-weight yet sturdy, and the colors are bright and easily seen. I initially purchased a bright blue one due to the green and orange being sold out. But now I am the owner of a bright green one, too! THAT'S how much I like these bags. Can't wait for my next opportunity to use it again. : )
