I think the Cupid is lighter than my BBW MAM. I wear both as shoulder bags with the longer strap.
A question for all you lucky Cupid owners out there - someone posted earlier that they found the Cupid heavier than a MAM, but is it as heavy as a BBW MAM? I'm tempted to go for it but want to make sure it's not too heavy for me (I find my BBW MAM a little heavy, but I think this also stems from my preference to wear it as a shoulder bag which it's not really designed for).
