We're no historians, but we're pretty sure the Poler Duffaluffagus Duffel Bag is the duffeliest duffel the world has ever seen. For one thing, it's pretty big. 54 liters, to be exact. While that isn't exactly carry-on size, Poler assures us that it will fit in an overhead, so you might be fine. The straps are made with the same stuff they use to make seatbelts, so it should have no trouble carrying whatever it is you need to carry. You can slide your business card into the plastic window on the side for positive identification, but we bet you won't see another one at baggage claim, unless you happen to be flying to or from Portland. As far as mobility goes, you can cram it full and wear it on your back using the hide-away backpack straps, or strap your skateboard to the bottom and transform it into a rolling gear bag.
