I can't think of a thing that's wrong with this small duffel.  I had to go work at a remote client site for nine months.  I have two months to go.  About every two months, I fly back home.  The initial leg from my work location is aboard a small regional jet.  This duffel slides right in the overhead without a problem.  Standard size carry-ons just don't fit.

The material is stout, I like the separate compartment for shoes, and access to the various zippered compartments is easy enough.  The end pocket does not have a zipper, but I consider that a plus.  It's where I stash travel-related documents, breath mints, and whatever else I might want to grab quickly while standing in a line.

I fit three clothes changes, toiletries, and electronics in this duffel without a problem.

A most excellent experience.
