Casual travel calls for softer, more flexible bags. Backpacks take the weight and spread it over both shoulders, while freeing up both arms for taking photos, texting, or reading a map. Wheeled backpacks can really take the weight off your shoulders during those long hikes from the train station to the Hotel. Messenger bags or Day Packs are great travel companions for daily use and excellent for carryon travel. Kaehler Worldtraveler has a great selection of quality bags to get you around town or around the world.
