I’m biased as I only own the nano belt, but I absolutely love it! It is so lightweight and looks great crossbody, on crook of arm and handheld! The nano luggage seems well made but I feel it’s a little heavy for me. I also don’t like the robot face look...less timeless in my opinion even though lots of bloggers would say it is timeless, classic in design. Trio, I’ve heard, protrudes from the body if you fully utilize the compartments. I like the quality of leather but this bag just looks kind of “meh” to me from a design perspective.
in the end, you’ll know what bag is right for you! Good luck!
