Our award-winning Flex luggage is designed with a wraparound expandable zipper for extra packing space when you need it. The Carry-On Flex is the smallest in our Flex collection—sized to fit all overhead bins and perfect for any quick trip. Unzip the Flex feature for an extra 2.25" (6 cm) of space to fit any last-minute items. Plus, enjoy the same features you know and love about our Classic Carry-Ons, including a durable hardshell and a signature interior compression system that helps you pack (and protect) more. Details like an ultra-sturdy handle, underside grab handle, and premium 360° wheels make it easier than ever to maneuver and lift your suitcase. It's a best-of-both-worlds type of thing.
