If you travel a lot or spend time outside between classes, you need to have a protective cover for your stuff. Whether you have a computer, textbooks that you need for class or an important business document, everything that you carry needs to be sheltered from the elements that you face on a daily basis.
A leather duffel can be a stylish accessory that makes you look good while also helping you to stay organized as you go about your day. A quality bag can also make it easier to carry goods without hurting your back or your shoulder. Most bags come with a strap that you can use to carry the bag with your hands or a padded strap that won't hurt your shoulder if you don't want to carry it.
The bag will be perfect when you go to the gym and need something to keep your clothes in while you workout. If you go to a public gym, you may not want to throw your clothes in a public locker or risk them touching the floor. It adds another layer of protection for your favorite work shirt to ensure that you don't smell like a locker room when you get to where you need to go after you are done exercising.
