This travel duffel is well designed and highly functional. Our entire family loves this line of Eddie Bauer wheeled duffels and carry bags. We own four of the large size and use them all the time for travel. Daughter in college also has the medium bag and carry duffel - uses them all the time for trips back and forth. They have survived many international trips with no damage whatsoever. There are plenty of pockets, inside and out, to store and organize clothing and incidentals.The in-line-skate wheels are extremely durable and they are well protected (in a smartly designed wheel-well) from baggage handler damage - these won't break off like swivel wheels. The wheels are at the outside edge of the bag, so it is not at all "tippy" as some other bags we have tried. When laid on its back, the hard-shell impact-proof back forms a solid tray (very similar to the trays the FAA uses through security checks) and this protects the contents when laid on its back in baggage checking, handling and on carousels.At first, I did also experience that zippers could catch fabric and bind (as one reviewed pointed out). This is a common problem for zippers on nylon bags and garments. How many or you have had this happen on a rain jacket or wind breaker? There is a very simple solution that prevents this from happening. Grasp the zipper pull with your thumb and index finger, while holding your middle finger on the inside of the zipper just ahead of the zipper pull. As you operate the zipper, your middle finger pushes the fabric out of the way and the zipper will never bind. We have never had a zipper bind when we take this simple precaution.We highly recommend these wheeled duffel bags. As another reviewer stated, they have also replaced our standard luggage. Eddie Bauer's "Lifetime Guarantee" makes this purchase an easy one - EB always stands behind its products.
