Osprey's Ozone Convertible 28 Rolling Gear Bag has a capacity large enough for week long trips. It 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 comfort 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.
