Bought to use as additional luggage to store gifts on our return from overseas. My husband and I traveled light with just one carryon bag each. I stuffed this folded up duffel bag into my small carryon-it didn't take up any room! Yay!

It arrived in a self zipped, small square bag. Whats cool is the bag unzips into the actual duffel bag so its not a separate carry bag. Its seemed flimsy. We packed the bag (holds quite a lot!) until we almost couldn't zipper it close. We were worried it would burst especially in airport transit. To our surprise it was in perfect condition on pickup surviving three flight changes. No busting of the zipper, no tears in the fabric. Impressive. What was even cooler was when we unpacked it, it was easy to self zip it back into the original small square. Usually its almost near impossible to zip similar items back to the original packaging. Definitely recommend!
