An anti-lose rope clips between adult and child in a crowded terminal, the detail that separates this set from a plain carry-on. The retractable rod stops at 2 heights so a 3-year-old and an older sibling can both pull it comfortably, and 4 universal wheels glide over tile, carpet or a boarding ramp. A hardshell of PC and ABS resists scratches and rain, while the backpack uses wear-resistant 600D polyester with a side pocket for a water bottle and a front pocket for pencils. The suitcase interior has cross straps and a zippered compartment to hold shirts and shoes apart. The pair weighs 2.5 kg, a load a small child can manage with the shoulder straps.
