DELSEY Paris Helium DLX Softside Luggage Under-Seater with 2 Wheels

Great carry on. i chose it as a wheeled carry on that was a little smaller than some, and therefore unlikely to be challenged for size limits. I like the fact that it has a strap at the back and so can be placed on top of a suitcase and wheeled all as one. The opening zip is slightly awkward to use because of its curved course, but thats only a small thing.
