The pack bag member may be releasably attached to the cart frame by fabric fasteners and further secured by strap members. A lightweight tubular bag frame may be carried within the bag member for maintaining the bag in a predetermined shape and allowing the bag to stand on end independently or when secured to the cart frame. The pack cart frame includes a flexible strap handle for pulling the cart behind the user and a pair of shoulder straps, one being provided with a quick release buckle for allowing the pack cart assembly to be easily installed and removed from the shoulder mounted carrying position. The wheels may be quickly removed from the cart frame and stored in the pack bag.
