Since the EROL is so infamous, I assume that a lot of you have one! Can you tell me if the Mini size is too small to use for anything besides lunch? I see the dimensions on the webpage but I'm bad at visualizing these things... I would want to use it to carry a small wallet, 10 oz water bottle, sunglasses, keys and a Moleskine notepad... Do ya'll think I should get the big one or small? It would be for just toting around town on errands or on weekends when I don't need to carry a lot. I'm worried I'd look like a 10 year-old if it's too small. I have a lot of navy in my wardrobe, but I'm actually leaning towards the yellow. It's so summery. Sorry if there is already a thread about this. I searched and didn't see one, but please correct me if I'm wrong. I'm in Maine right now and it's thundering like crazy outside, btw! Have to do something to distract myself.
