Columbia Sportswear Axel 68 Rolling Duffel Bag

This is not a durable material. I have this bag and it got big scuffs in the material on the first flight. It's made out of a soft, pliable rubber that rubs off if your packed items (books, toiletry bags, tampon boxes, charger) inside make the slightest corner or awkward bulge- it's like they'll poke right through it. I'm much more careful to pack clothes on the outer layer now (pain in the neck), but still every trip I make it gets more and more deep scuffs while in transit from normal airline handling. Also- even though most of the bag is made of waterproof material, the wide stretchy panels next to the zipper wick water in easily, soaking everything inside. At lease if you pack with the clothes under these to avoid getting holes in the luggage, your books might stay dry. Overall- this comes close on a lot of measures, but really misses the marks on some important ones. I expect it might last me a year at most of hard travel before it gets too many holes in it to bother duct taping.
