I posted this on another forum and didn't get any replies - maybe this one is more active... Anyway, I'm considering the Saleya MM or the Cabas Mezzo to use as a carry-on travel tote. Would either have adequate roominess? I prefer a zipper so either would work. I like that the CM stands up nicely on it's own but is the Saleya a little floppy when not filled? The boutique was O/S on the Saleya MM but I looked at the GM and it was very floppy and didn't stand up on it's own at all - I thought it looked messy. Any comments on the MM's "floppiness". I like the leather on the Saleya and am concerned with CM vachetta getting dirty and scuffed - comments on that would really be appreciated since my next trip with one of these bags will be a sailing trip. Since I haven't seen them side by side which is roomier?
