I remember reading something about these bags a while ago, and the overall impression I came away with was that these bags are not very heavy duty- more a fashion piece than a really solid functional thing. I do like the idea of bags that are made to hold lenses, film, and other little accessories, and not cameras (which would be in use, hung over a shoulder, etc.) but I don't think this is it.
As for showing them my sac- well, I don't think we know each other well enough...
