A backpack, to be carried on the back of a user, that includes a hollow shell and a lid. The hollow shell has a substantially rigid bottom wall, and a sidewall that extends up continuously from a periphery of the bottom wall and terminates in an annular upper edge. The annular upper edge defines an opening into the interior of the hollow shell. The sidewall has a leading end and a trailing end and is also substantially rigid. A lid is rotatably connected to the shell. The lid is rotatable between an open position for exposing the opening and a closed position for covering the opening. A pair of shoulder straps are connected to the shell for supporting the backpack on the back of the user so that the bottom wall faces the user's back. A plurality of pads are affixed to an outside surface of the bottom wall. During use, the plurality of pads support the bottom wall in spaced relation to the user's back thus maintaining a ventilation gap between the bottom wall and the user's back. The sidewall and the lid together form a backpack upper surface that has a streamlined aerodynamic shape, such that when air flows past the leading end, some of the air is directed through the ventilation gap formed between the bottom wall and the user's back, and some of the air is directed along the upper surface with minimal wind resistance.
