Does anyone make just a basic (carry-on size) soft suitcase with no wheels, just a carry handle? Just a regular clam-shell style opening with a spacious main compartment, no extra side pockets, organizers etc. I am not looking for a "duffel" top loading style, just something I can lay flat and fully open the lid revealing a spacious interior, and that's it. If it has a trolley sleeve too that would be nice but not required. Thanks for your help!
