I always carry one in my purse because you never know when you may need it. Since they don't weigh anything you can fold them into a ball and carry them everywhere.They are very resistant and can hold up to 25 pounds.

These reusable shopping bags have helped me in all my travels, in the airport to carry my books and magazines, in the supermarket, the beach or for a picnic at the park. They can be washed without any problem and they come in a large variety of colors.
