This clever transport and protection bag with wheels converts any backpack or duffle bag into rolling luggage. It keeps your gear clean and safe during flights and the rest of your trip. The zippered access to the suspension system of your backpack allows for a swift switch between rolling and carrying. The roll-top closure of the bag allows volume adjustment for packs between 40-80L or duffle bags up to 100L. When not in use it packs down to 36 x 30 x 24 cm and only weighs 1.68 kg despite the durable and silent wheels.
