I think the cambon line is quite durable!! One time my bowler was smooshed by a chair (don't know how it happened, I went home and there was a chair on top of my bag!!!!) and when I removed it, there were some creases but no scratches or anything!
I think it'll be safe for everyday use. The only thing I would advise is that if you have a light color bag (beige, pink, white), make sure the black straps arent resting against the bag when you store it.
