This is a great bag for heavy groceries, books, small musical instruments, great for an overnight trip and anything else you can think of. It is lined with an inner pocket for your keys, money, ID or whatever else you want to put in there. It is machine washable and please put in a laundry bag when washing and lightly dry. It's a beautiful fabric for an environmental friendly bag. This bag can hold quite a bit of weight. It has a box bottom of which you can put a piece of cardboard in to keep a shape. Or you don't have to. I remove the cardboard when I go to Trader Joe's and just fill it up. It can hold quite a bit of sweet potatoes lemons avocados and this padded shoulders make it a little bit easier ones body.
