Abstract: Embodiments of a pack system for bearing animals includes a large support panel for contacting a substantial area of the animal upon which it is placed. Preferably, the central longitudinal axis of the support panel is curved to contour to the animal's back. A plurality of bags or other carrying devices are connected to the support panel near four comers of the support panel, so that the weight of the load is widely-distributed on the animal, instead of on a small surface area of the animal behind the saddle as is the case in most conventional saddle bags. Fastening straps may be included to extend around the chest and the rear quarters of the animal to further stabilize the support panel with its bags, and the saddle which rests on the support system. Unlike conventional saddlebag systems, the invented system does not require attachment to or support from the saddle.
