The ZDX 21 International Carry-On Wheeled Duffle offers the best of everything, combining the packability of a duffle with the convenience of a wheeled carry-on. Slightly smaller than a regular upright carry-on, it boasts our patented Outsider handle for a flat, roomy interior, plus an easy-access exterior pocket to hold items for security checkpoints and an outside battery pocket so you can keep charging your phone as you roll along to your weekend adventure. Perfect for the light on the go packer.
