Our award-winning Flex luggage is designed with a wraparound expandable zipper for extra packing space when you need it. The Large Flex is our checked suitcase designed for extra-long trips (2+ weeks). With a Flex feature that expands for an additional 1.75" (4.5 cm) of space, you'll never have to worry about squeezing in a few more outfits or fitting in those extra souvenirs. Plus, enjoy the same features you know and love about our Classic Carry-Ons, including an ultra-sturdy handle, underside grab handle, and premium 360 wheels to make it easier than ever to maneuver and lift your suitcase.
