When traveling with a rolling suitcase and either a laptop bag or backpack, many people want to combine the two items. This frees a hand for a coffee and takes a weighty strap off your shoulder. But if you’re concerned about your shoulder, its important to do it the right way. The most common approach is to the stack the smaller bag on top of the suitcase, either leaning it against, or strapped around the handle. However, this places more weight and pressure on your shoulder while you’re rolling your bag. The best approach is to use a clip (many suitcases have them built into a zippered pouch on top) to hang the bag off the front.
