More elegant than a conventional backpack and more casual than a typical office bag: the Ortlieb Commuter Daypack Urban Line is a modern city backpack for individualists. Although the robust Cordura fabric looks and feels like woven fabric, it is absolutely waterproof. The clever TPU back padding features smart ventilation channels and offers outstanding carrying comfort. The practical roll closure ensures quick access to the main compartment and the padded sub-compartment where your notebook and tablet are ideally stowed for safekeeping.
