Two coordinated pieces share this kids luggage set, a rolling suitcase with flexible 360° universal wheels and a lightweight backpack that attaches to the suitcase with an elastic band so children can manage both together. The suitcase offers a spacious main compartment plus a side zipper pocket for sorting clothes, books, toys, snacks, and small items. A 3-level telescoping handle and adjustable backpack shoulder straps match different kid heights. ABS with a frosted film resists water, abrasion, and impacts.
