Two and half pounds before one puts her stuff inside seems heavy to me. Having said that I have not weighed my bags (and now, I'm curious!) but gone by how it feels, alone. That Borough feels weighty. And when I packed it? And then made the utterly stupid mistake to carry it to a track and field event…GAH. --> I should have known better.
I think it will be fine to carry to work. And it's a gorgeous bag. I could do without the center zippered compartment, though.
