Adaptable, durable and lightweight, this hard case suitcase set is like having two spinners that do the work of three! The Travelpro® Runway® 2-piece Hardside Carry-on & Convertible Medium-Large Checked Expandable Spinner Set includes a hardside carryon suitcase and a size-adjustable check-in hardside spinner that converts from a medium- to a large-size check-in suitcase when fully expanded. Created to serve separate functions, both of these lightweight yet durable bags are constructed with a blend of PC/ABS for lasting resilience and finished with a textured surface that minimizes the appearance of scuffs or scratches. This 2 piece set offers lined interiors with an interior divider panel, accessory pocket, and adjustable hold down straps to keep packed contents organized and in place. Smooth-gliding, 8-wheel spinners rotate 360° to provide superior maneuverability led by height-adjustable handles with patented ProGrip™ design for hand comfort. Size and expansion is where these bags differ most. The carryon luggage with spinner wheels has been sizer bin tested to fit in the overhead bins of most major domestic airlines and offers a 2” expansion option that maximizes packing capacity. The Convertible Medium-Large Check in luggage is a medium-sized bag that features a unique 3” expansion option that increases the bag’s capacity and size to a large check-in spinner (62 linear inches). No need to buy a medium and a large expandable suitcase – or even decide which to bring. Whether you over pack before departure or over shop at your destination, you will never have to worry about running out of space with this 2 piece hardshell luggage set!
