I have a major issue with the side ties on my Neverfull MM staying cinched. I don't overfill my bag, but usually carry a vernis zippy wallet, mono cosmetics pouch, checkbook, sunglasses, keys, and papers. It seems that whenever the items shift toward one side of the bag they put pressure on the sides causing the ties to loosen open. I am constantly fixing the ties. If the bag is just sitting (as it is under my desk all day), no problems. I'm a big fan of unstructured bags, so it hasn't soured me on this particular bag, but it can be a bit annoying.
