Thanks for the explanation, luv! I don't mind weight so much since I drive from suburbs to university parking lot and short jaunt inside. When with my kids I just take woc with me because anymore than that and I'm totally burdened(I wear the 14 month old 29lb girl and need to lift the even heavier bigger girl in and out of car and shopping cart seats so bag stays in car unless there's a poop diaper situation).
Sans kids the frankie is perfect and I drive so weight is fine and I can even ball up my jacket or cardigan and stash it in there if sitting in close quarters in a stuffy room, frankie is like a Mary poppins carpet bag magical thing!
I actually have a leather bag with almost every single detail the same as frankie and it is lighter in weight, so I guess frankie isn't a feather. But then again the leather bag is crazy light (but an unstructured puddle and I adore how frankie stands up just the same empty as full!!!).
