The Frequent Flyer Hardside Carry-On combines our practical know-how with our technical thinking. The look of this upright is smooth and uninterrupted, with the latest advances in molding technology and super-recessed wheels and haul handles contributing to more packing space. What's more, hidden ID tags reveal a toolkit that includes a USB port for connection to a power pack (purchased separately). Combine all this with a 100% virgin polycarbonate shell with puncture-resistant double racquet coil YKK® zippers and an integrated Travel Sentry® Approved combination lock, and you have a strong, reliable and future-facing carry-on.
