I am not a big fan of the U shaped opening of the Kayla https://www.ebags.com/product/ebags/...sb-port/353311 It is a Steal of the Day at $89 which is a nice price.

I have used the Baggallini rolling tote. I think I purchased it in a steel gray color on ebay for about $100. It is a clown car of a bag- fits more it in than I would have thought would fit.

The travel pro under seat https://www.travelpro.com/maxlite-5-...rseat-carry-on also has a big U shaped opening so perhaps that is a feature you like.
