Despite the airlines’ inexplicable checked bag fees, sometimes it’s impossible to fit a week’s worth of clothes into a tiny carry-on and we’re forced to go with something a little bigger. If we absolutely must subject our luggage to baggage handlers throwers, conveyor belts, and TSA searches, it should be able to withstand some abuse and stand out from the masses of cheap black nylon rollers. We like polycarbonate shells for being able to take a punch and the four spinner wheels for easier maneuverability. These are four of our favorites for making sure your belongings arrive intact for years to come.
