Can you tell me how you like it? I've been really looking at the large Ergo tote but really need a shoulder bag with a zipper. I'd like to know how it stays on your shoulder, is it light, what does the lining look like? I'm going to be traveling a lot this summer and would like a good sized bag that is shoulder style with a zip. Of course, with the PCE, I may just have to pick up a tote, too! If you would post pics, I'd be happy to send a margarita your way!
