Yes, the large duffle is huge! It does hold a lot but you don't have to fill it up (I like the slouch when it's not packed). The regular duffle is very roomy too though. I would look in the duffle clubhouse thread to see if you can find mod shots of people wearing both sizes to see which you like better. I will include a couple of mine so you can see a few. For some reason I didn't take photos of the black cherry or navy as crossbody or long shoulder bag (sorry).
