yes it is heavier than say, the Alma.
BUT the ManhattanGM is Gorgeous (well so is the Alma) and is a traffic stopper whenever I carry it out.
I carry usually just a few items in it: wallet, glasses, sunglasses case, and another wallet/card holder, some papers. I really think of these LV's as travel bags, so if I need to stuff more into the GM I do.
Good luck and have fun with your decision and shopping.
