This bag is shown standing up in the picture, but honestly, they had to have supported it somehow. The bags are so flimsy! And, there isn't even a reinforced bottom, so the whole thing sags when you load it up and then try to carry it. Might as well just get those free plastic bags for all the good this will do to keep your groceries from rolling around in the car. However, they are lined with the standard cold/hot insulating lining, so, if you can keep your groceries in the bag, they are likely to stay hot or cold.
