Pump & milk storage bags

Jess
Hi
I'm going to try to pump when I return to work in a few weeks and am looking for recommendations as to the best bags to carry the pump and expressed milk etc. I have to carry a laptop already and have a larger laptop and purse in one bag and want to avoid looking like a crazy bag lady if possible :)
Has anyone found any good solutions?
EDIT: Sorry I should clarify that I am looking for bags to carry the equipment and milk etc to/from work in, not what to pump into (I have the Kiinde system already 🙂)
