Osprey's Ozone Convertible 22 Rolling Gear Bag has endless features for practically any weekend trip. This carry on features large wheels with a retractable T handle, and padded shoulder straps that convert the Ozone from a rolling bag into a backpack. Its Highroad LT Chassis includes a padded back panel for comfort, an ultralight aluminum frame for stability, and an injection molded ABS base for support. The Ozone also features a detachable day pack for extra convenience once you've reached your destination. The endless features part comes in the Ozone's massive pocket configuration. There's an easy access top zippered pocket for liquids and valuables and a heat embossed pocket that protects glasses and electronics from scratches. There's also a large front panel pocket for magazines. Inside, there are multiple mesh pockets full length and small and plenty of organizers to keep practically every item separate from one another. External dual upper and lower side compression straps secure your gear whether you're running to the plane or driving across the state.
