Pink shell, 3-stage handle: this pair is built to grow with a child, the pull bar locking at 26, 30.5 or 35 inches as they get taller. The 14 by 8 by 18 inch case meets carry-on limits and turns on 4 universal wheels, so it follows beside a child rather than being dragged. Cross straps and a zipped pocket inside stop folded clothes from tumbling when the lid opens. The 11 by 4 by 13 inch backpack holds a tablet, snacks and a small toy across 2 compartments, with adjustable shoulder straps and an elastic band that slides over the suitcase handle. At 5.5 lbs for both pieces, a child can handle the set through an airport alone.
