Anyone have personal experience with the North Face Doubletrack 21? Dimensions are listed as 22x14x6 (for the backpack, not including the seperating day-pack), and I've had no issues on NW/DL planes, yet thought I'd ask. Yet the wheels, bottom handle, and top edge has always concerned me in new situations. Will report back personal experience, if noone else has reports. Thanks.
