This two-piece ABS set—20" carry-on plus 24" checked—matches down to the wheels, letting you travel together or split up depending on trip length while keeping the same sleek look. Feather-light yet impact-tough, the shells shave pounds off your allowance so you pack more without paying for heavy baggage. A built-in 3-digit TSA lock guards your gear key-free, and the smooth expandable spinners glide silently from curb to carousel for effortless, secure journeys every time.
