• a seat comprising a flexible sheet coupled to and extending between the main frame and the seat frame, the seat being looped around a distal portion of the seat frame, the seat being configured to support a user on a front side of the seat when the seat frame is in the seat position, the seat being configured to support a load on a rear side of the seat when the seat frame is in the pack position;
• a support leg assembly mounted to the main frame, the support leg assembly comprising:
• a leg frame pivotally mounted to a back side of the main frame, the leg frame being positionable in a use configuration in which the leg frame extends downwardly and rearwardly from the main frame, the leg frame being positionable in a stored configuration in which the leg frame extends from a leg pivot upwardly with respect to the main frame over the back side of the main frame;
• a use retainer configured to retain the leg frame in the use configuration, the use retainer comprising a leg strap and a leg buckle, a first leg strap segment of the leg strap being coupled to the leg frame, a second leg strap segment of the leg strap being coupled to the main frame, the first and second leg strap segments of the leg strap being couplable to each other via the leg buckle;
• and
• a storage fastener configured to retain the leg frame in the stored configuration, the storage fastener comprising a storage strap coupled to the main frame, the leg frame being positionable between the storage strap and the main frame to be secured in the storage configuration;
• and
• a harness assembly mounted to the main frame and configured to attach the main frame to the user, the harness assembly comprising:
• a pair of shoulder straps mounted to the main frame, the shoulder straps being laterally spaced from each other with respect to the main frame and being configured to hang on shoulders of the user;
• a chest strap coupled to and extending between the shoulder straps, the chest strap being configured to be positioned around a chest of the user;
