We just came back from overseas. Going to 4 countries, and many stopovers, these bags have been a God-send. We bought several of these and other eBags cube sets (the 3-size set), one color per person to make packing easier. Going through security check-out was a breeze. Each large bag can fit many clothing. It was easy to organize our stuff and easy to pack/unpack the content. I would recommend these bags in a heart beat. They are worth every cent.
