Duffel bags are often seen as more rugged and durable than backpacks, since they’re typically made of tougher materials such as canvas or nylon instead of fabric like most backpacks. They also tend to be less expensive than traditional backpacks, making them an ideal choice for those who don’t want to spend too much money on their bag. Furthermore, duffel bags offer plenty of space for packing clothes and other items without having to worry about overstuffing the bag because they usually have larger pockets or compartments compared with traditional backpacks. On the other hand, if you need something more lightweight that can fit into tight spaces such as an overhead bin in airplanes, then a backpack would probably be your best bet. Backpacks are also easier to carry around due to their adjustable straps which allow you customize how tightly it fits against your body depending on what kind of activity you plan on doing while wearing it.
