Duffel bags are a great way to take your belongings with you, whether you’re heading on a trip or simply to the gym. Suitcases are great, but thanks to their hard, outer shell, they can’t hold as much stuff, and can’t always fit wherever you have space. Thanks to duffel bags, this isn’t an issue. Duffels are soft, thus can pack more things and fit in a variety of spaces. In addition, the handles on duffels make them easy to carry.
