Both look good, I would just keep a watch on the weight of the bag empty knowing you will be adding a good bit of weight to it. I always carry a backpack that is basically weightless to start with but have never needed it to be a cooler type product. I am interesting in finding out what you chose and how it worked when you get back. We usually just take a water bottle and granola bars. I have too many memories of hauling bottles, formula, and baby food when my boys were babies. That bag got really heavy when we were between stroller times!
