Knowing what you want before you get to the store can help you zero in on the best items and avoid buying unnecessary luggage. Do you just need one piece to add to an existing set? Are you looking for a new pack for a backpacking trip? How big of a piece do you need?
Compare different types of luggage. Internal-frame backpacks, rolling luggage and duffel bags all have their own strengths and weaknesses.
Compare brands. Keep in mind that the most expensive designer luggage may not be the most durable or functional. Spending a little less on a generic brand may actually yield better results.
Try rolling or carrying any luggage that you may purchase. Check how you like the handle and size of the piece. Try on packs to make sure that they fit comfortably and the straps adjust to fit you snugly.
Look for distinctive luggage. Half of the people on any given flight will have black, rolling suitcases. Make it easier to spot your gear by looking for luggage with a little color or a distinctive feature.
