I have a North Face backpack I got for free at work and use that as a carryon. Before I got that, I used a free tote I got from DSW about ten years ago - it's great because it has a zippered compartment on the bottom for shoes. |
Rimowa is absurdly expensive for what is just a normal carryon.
I have a Biaggi carryon that can convert to a checked size I like for trips—if I am bringing back souvenirs or work stuff, I can easily expand it and check. I can travel about a week with it. I also have an Biaggi under seat bag I love. When I travel I want all my stuff with me. Snacks, kindle, chargers, meds (I have a serious health condition and can’t risk being separated from meds). Neck pillow, chapstick, etc. I like it all within reach. It slides on the roller convertible carryon as well so I am not carrying anything. |
I buy Samsonite (usually it comes in a pack of a full sized suitcase and a small carry-on cabin suitcase) from Costco. Costs the same as buying one full-sized suitcase at any other store.
Normally, while travelling I need from 1-3 full sized suitcases and one carry-on cabin suitcase. So, I have a carryon for every full sized suitcase. I have been able to utilize the smaller carry-on cabin suitcases as storage for jewelry, important documents and medical gadgets repository at home. |
For bigger trips, I do check a large luggage. I try not to haul too much on the plane if I've already checked a luggage. I use a Tumi Just In Case Tote to carry a spare set of clothes among other things, and that bag has been very useful. |
No one actually read the OP. She wants a wheeled carryon that she can somehow attached to her wheeled checked bag.
Does such a thing even exist? |
If you have enough for a duffle why can't you just take a regular wheeled carry on? You can still attach it to your larger suitcase when you pick that up at baggage claim. NOt seeing why it has to be a duffle. |
I use a rimowa as my carry on and I fly charter/PJ. |
Save the histrionics. The CO2 for just about any single flight dwarfs the environmental impact of their suitcase. |
I’ve seen flight attendants with this setup. Underwear wheeled is keywords https://www.amazon.com/Hanke-Underseat-Suitcases-Lightweight-Airplanes/dp/B0CLLB4N38 Stacked seems tough though. |

Go with a backpack. I normally don’t check luggage but when I do I’ve found I need a backpack rather than a tote to distribute the weight. Mine is a Lo & Sons that I also use for work. I can also do a lightweight tote as my second item as long as my laptop and heavier items are in the backpack. |
Just searched on Amazon for something similar and this popped up:
KROSER Carry On Underseat Multi-functional, 16-inch Underseat It is basically a wheeled tote that stacks. Cheap but fills the need. |
