Delsey used to have a line called the Helium Breeze, which was the only 21" carry-on suiter that would allow my business suit and shirts to come out relatively unruffled if I left the clothes in dry-cleaner plastic. I have two of them, one is about nine years old and the other five. Both have been heavily used and still look good. However I just nosed around and it looks like Delsey has killed the line. Note these were two-wheelers, not four. This YouTube video shows how the suiter portion worked at about 3m:40s in the video.
